File Downloading Error in ASP.NET - C# from Gridview

Kindly Look at the error screen. I just want to download file from template field in gridview I saving file in server directory and file path in db.
any with this fix or proper new solution
<asp:GridView ID="GridView1" runat="server"
onrowcommand="GridView1_RowCommand">
<Columns>
<asp:TemplateField HeaderText="File">
<ItemTemplate>
<%--<asp:LinkButton ID="lnkDownload" Text = "Download" CommandArgument = '<%# Eval("filepath") %>' runat="server" OnClick = "FilesDownload"></asp:LinkButton>
--%>
<asp:LinkButton ID="LinkButton1" runat="server" CommandName="Download"
Text='<%# Eval("Path") %>' CommandArgument='Eval("Path")'></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
</Columns>
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "Download")
{ Response.Clear(); Response.ContentType = "application/octectstream";
Response.AppendHeader("content-dispositi­on", "filename=" + e.CommandArgument);
Response.TransmitFile(Server.MapPath("~/­File") + "//" + e.CommandArgument);
Response.End(); }
}

You need to follow the below steps:-
Add the TemplateField at the end as below.
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton ID="lnkDownload" Text="Download" CommandArgument='<%# Eval("file") %>' runat="server" OnClick="DownloadFile"></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
and in Code-behind do something like this:-
protected void DownloadFile(object sender, EventArgs e)
{
try
{
string filePath = (sender as LinkButton).CommandArgument;
System.Net.WebClient req = new System.Net.WebClient();
HttpResponse response = HttpContext.Current.Response;
response.Clear();
response.ClearContent();
response.ClearHeaders();
response.Buffer = true;
response.AddHeader("Content-Disposition", "attachment;filename=\"" + Server.MapPath("~/YourFolder/" + filePath) + "\"");
byte[] data = req.DownloadData(Server.MapPath("~/YourFolder/" + filePath));
response.BinaryWrite(data);
response.End();
}
catch (Exception ex)
{
throw ex;
}
}

How to Insert and edit from the grid-view on run time using resource file

I am working on resource files. I can now read resx file and get it populate the data into the grid-view. now here is my question now,
On a run time, i want to be able to edit the columns and also be able to click empty columns and click save to save my changes. How do i do that. please help me as i have tried many examples and it didn't work.
my code below,
private void btnNewfile_Click(object sender, EventArgs e)
{
for (int i = 0; i < oDataSet.Tables[2].Rows.Count; i++)
{
string comment = oDataSet.Tables["data"].Rows[i][2].ToString();
string font = Between(comment, "[Font]", "[/Font]");
string datestamp = Between(comment, "[DateStamp]", "[/DateStamp]");
string commentVal = Between(comment, "[Comment]", "[/Comment]");
string[] row = new string[] { oDataSet.Tables["data"].Rows[i][0].ToString(), oDataSet.Tables["data"].Rows[i][1].ToString(), font, datestamp, commentVal };
Gridview_Output.Rows.Add(row);
}
oDataSet.Tables.Add(oDataTable);
oDataSet.WriteXml(PathSelection);
}
Save button(the user must be able to save the file created or edit to any location (C drive))
private void btnSave_Click(object sender, EventArgs e)
{
SaveFileDialog saveFileDialog1 = new SaveFileDialog();
saveFileDialog1.InitialDirectory = #"C:\";
saveFileDialog1.Title = "Save Resource Files";
saveFileDialog1.CheckFileExists = true;
saveFileDialog1.CheckPathExists = true;
saveFileDialog1.DefaultExt = "resx";
saveFileDialog1.Filter = "Save Resource Files (*.resx)|*.resx";
saveFileDialog1.FilterIndex = 1;
saveFileDialog1.RestoreDirectory = true;
if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{
//nere i need the user to save to any location he want not textbox.
txtOutputfile.Text = saveFileDialog1.FileName;
}
//oDataSet.Tables.Add("Data");
oDataSet.WriteXml(PathSelection);
versionIncrement();
MessageBox.Show("Successfully added ");
}

See if the below code helps.

Add new record to Telerik RadGrid

I have the following Telerik RadGrid, which I'm using in C#:
<MasterTableView Width="100%" EditMode= "InPlace" ClientDataKeyNames="menuID" CommandItemDisplay= "Top">
<Columns>
<telerik:GridBoundColumn DataField="Name" HeaderText="Name" SortExpression="Name" UniqueName="Name"></telerik:GridBoundColumn>
<telerik:GridTemplateColumn UniqueName="Type" HeaderText="Type">
<ItemTemplate>
<asp:TextBox ID="Type" Text='<%# DataBinder.Eval(Container.DataItem, "Type") %>' runat="server"></asp:TextBox>
</ItemTemplate>
<EditItemTemplate>
</EditItemTemplate>
</telerik:GridTemplateColumn>
<telerik:GridTemplateColumn UniqueName="List" HeaderText="List">
<ItemTemplate>
<asp:CheckBox ID="List" runat="server" Checked='<%# DataBinder.Eval(Container.DataItem, "List") %>' />
</ItemTemplate>
<EditItemTemplate>
</EditItemTemplate>
</telerik:GridTemplateColumn>
<telerik:GridTemplateColumn UniqueName="loadAtStart" HeaderText="loadAtStart">
<ItemTemplate>
<asp:CheckBox ID="loadAtStart" runat="server" Checked='<%# DataBinder.Eval(Container.DataItem, "loadAtStart") %>' />
</ItemTemplate>
<EditItemTemplate>
</EditItemTemplate>
</telerik:GridTemplateColumn>
</Columns>
</MasterTableView>
The grid is populated with data, and working normally when editing the data.
But when I click on the Add New Record button provided by Telerik, then an empty row is added without any TextBox or CheckBox in the columns to edit in the new Row added. It's just an empty row. I presume that I have to create the controls dynamically in the called ItemDataBound event, but I didn't manage to find the actual code for this.
How do I solve this?

Please try with the below code snippet.

Hope this would help you :-)

I'm not really a fan of any of these solutions because they require the use of Session. Session has it's place but I believe it's used more as a crutch.
You're already sending the RadGrid information back to the server-side via ViewState due to the PostBack so why not use it's information instead of relying on an in-memory store.
Example of Adding and Removing an item from a Grid. Yes, it does require iterating items to rebuild a List but it's an alternative to Session so I believe it has merit.
protected void addValueToRecentTagList(string text)
{
List<string> items = new List<string>();
foreach(GridDataItem row in RadGridNewTags.Items)
items.Add(row["tag"].Text);
items.Add(text);
RadGridNewTags.DataSource = items;
RadGridNewTags.DataBind();
}
protected void removeValueFromRecentTagList(string text)
{
List<string> items = new List<string>();
bool rebind = false;
foreach (GridDataItem row in RadGridNewTags.Items)
{
if (row["tag"].Text == text)
rebind = true;
else
items.Add(row["tag"].Text);
}
if (rebind)
{
RadGridNewTags.DataSource = items;
RadGridNewTags.DataBind();
}
}

You have to insert a control in the EditItemTemplate to display in Edit or Insert mode.
Or you can add an InsertItem Template and place a control in there:
<telerik:GridTemplateColumn UniqueName="loadAtStart" HeaderText="loadAtStart">
<ItemTemplate>
<asp:CheckBox ID="loadAtStart" runat="server" Checked='<%# DataBinder.Eval(Container.DataItem, "loadAtStart") %>' />
</ItemTemplate>
<EditItemTemplate>
<asp:CheckBox ID="cbxEditLoadAtStart" runat="server" Checked='<%# Bind("loadAtStart") %>' />
</EditItemTemplate>
<InsertItemTemplate>
<asp:CheckBox ID="cbxInsertLoadAtStart" runat="server" />
</InsertItemTemplate>
</telerik:GridTemplateColumn>

Thanks,

Try using Button editbtn = (Button)sender; Rather than Button EditButton = (Button)gvGroupMaster.Rows[(((GridViewRow)(((Button)(sender)).Parent.BindingContainer))).RowIndex].FindControl("btnEdit");

How to transfer item from one datalist to other datalist?

I have a datalist
<asp:DataList ID="dlstImage" runat="server" RepeatDirection="Horizontal" RepeatColumns="5"
CellSpacing="8">
<ItemTemplate>
<asp:ImageButton ID="Image" runat="server" ImageUrl='<%#"~/Controls/ShowImage.ashx?FileName=" +DataBinder.Eval(Container.DataItem, "FilePath") %>'
OnCommand="Select_Command" CommandArgument='<%# Eval("Id").ToString() +";"+Eval("FilePath")+";"+Eval("Index") %>' /><br />
<asp:Label ID="lbl" runat="server" Text="Figure"></asp:Label><%# dlstImage.Items.Count + 1%>
</ItemTemplate>
</asp:DataList>
In which i am binding the image after uploading through uplodify upload, now i have one more datalist
and two btn up and down,
<asp:ImageButton ID="ibtnMoveUp" runat="server" ImageUrl="~/App_Themes/Default/Images/moveup.bmp"
Style="height: 16px" ToolTip="MoveUp The Item" />
<asp:ImageButton ID="ibtnMoveDown" runat="server" ImageUrl="~/App_Themes/Default/Images/movedown.bmp"
ToolTip="MoveDown The Item" />
<asp:DataList ID="dlstSelectedImages" runat="server" RepeatDirection="Horizontal"
RepeatColumns="5" CellSpacing="8">
<ItemTemplate>
<asp:ImageButton ID="Image" runat="server" /><br />
<asp:Label ID="lbl" runat="server" Text="Figure"></asp:Label><%# dlstImage.Items.Count + 1%>
</ItemTemplate>
</asp:DataList>
My both datalist is in the same webuser control, datalist1 and datalist2 and I have 2 btn up and down, when i select one image from datalist1 and click on down btn then the selected image should move to datalist2. How to do that? someone please help me,

You need to handle the ItemCommand event of one DataList in which you have to copy the selected data (image) into another dataSource of two DataList and remove that item from the datasource of one DataList.
Markup:
<asp:DataList
ID="DataList1"
runat="server"
OnItemCommand="PerformMove"
>
<ItemTemplate>
<br /><%#Eval("Text") %>
<asp:Button ID="btn1"
runat="server"
Text="Move"
CommandName="cmd"
CommandArgument='<%#Eval("Text") %>'
/>
</ItemTemplate>
</asp:DataList>
<asp:DataList ID="DataList2" runat="server">
<ItemTemplate>
<br /><%#Eval("Text") %>
</ItemTemplate>
</asp:DataList>

Session["list2"] = list2;
DataList1.DataSource = Session["list1"];
DataList1.DataBind();
DataList2.DataSource = Session["list2"];
DataList2.DataBind();
}
}
protected void PerformMove(object source, DataListCommandEventArgs e)
{
if (e.CommandName == "cmd")
{
List<Data> list1 = Session["list1"] as List<Data>;
List<Data> list2 = Session["list2"] as List<Data>;
list1.Remove(new Data() { Text=e.CommandArgument.ToString() });
list2.Add(new Data() { Text = e.CommandArgument.ToString() });
DataList1.DataSource = Session["list1"];
DataList1.DataBind();
DataList2.DataSource = Session["list2"];

I am using this code and its working well for me.
ArrayList ImgArry = new ArrayList();
path = objGetBaseCase.GetImages(TotImgIds);
ImgArry.Add(SelImgId);
ImgArry.Add(SelImgpath);//image name
ImgArry.Add(SelImgName);//image path
//path.Remove(ImgArry);
List<ArrayList> t = new List<ArrayList>();
if (newpath.Count > 0)
t = newpath;
t.Add(ImgArry);
newpath = t;
for (int i = 0; i < newpath.Count; i++)
{
ArrayList alst = newpath[i];
newtb.Rows.Add(Convert.ToInt32(alst[0]), alst[1].ToString(), alst[2].ToString(), i);
}
dlstSelectedImages.DataSource = newtb;
DataBind();
path = objGetBaseCase.GetImages(TotImgIds);
for (int i = 0; i < path.Count; i++)
{
ArrayList alst = path[i];
tb.Rows.Add(Convert.ToInt32(alst[0]), alst[1].ToString(), alst[2].ToString(), i);
}
dlstImage.DataSource = tb;
DataBind();
