I'm use grid view for show recent messages...there use datasource...
<asp:GridView ID="GridView1" runat="server" AllowPaging="True" Width="586px" AutoGenerateColumns="False"
DataSourceID="SqlDataSource1"
onselectedindexchanged="GridView1_SelectedIndexChanged"
onrowcommand="GridView1_RowCommand">
<Columns>
<asp:CommandField HeaderText="show" ShowSelectButton="True" />
<asp:BoundField DataField="user_id" HeaderText="user_id"
SortExpression="user_id" />
<asp:BoundField DataField="user_name" HeaderText="user_name"
SortExpression="user_name" />
<asp:BoundField DataField="sender_mail" HeaderText="sender_mail"
SortExpression="sender_mail" />
<asp:BoundField DataField="message" HeaderText="message" ReadOnly="True"
SortExpression="message" ControlStyle-Width="70px" ControlStyle-Height="25">
<ControlStyle Height="20px" Width="50px" />
<HeaderStyle Height="10px" Width="70px" />
<ItemStyle Height="20px" HorizontalAlign="Left" Width="70px" />
</asp:BoundField>
</Columns>
</asp:GridView>
there in my database if message is too long then it show in one field...
ex:-msg is 'hi how are you'
it show full msg......but i show data only 'hi how...'
i'm also try set width and height but not work.
You can use a template field instead of the boundfield.
<asp:TemplateField >
<HeaderTemplate>Message</HeaderTemplate>
<ItemTemplate>
<%# Eval("message").ToString().Substring(0,10) %>
</ItemTemplate>
<EditItemtemplate>
<asp:textbox id="Textbox1"
text='<%#Eval("message")%>'
width="90"
runat="server"/>
</Edititemtemplate>
</asp:TemplateField>
Here we are taking a substring of the message (10 characters only). you can modify to suit your needs.
You can do this by adding method to your code that take the msg from DB or just string then you make on that string whatever you want(cut the string at specific index then add ...). And that method then return the processed string back
public string cutString(string msg)
{
int msgLength = 100;
return msg.Substring(0, msgLength) + "...";
}
<asp:Label runat="server" Text='<%# cutString(Eval("message").ToString())%>' />

I'm having a GridView to display few columns. when I click the edit button in the GridView, it displays a DropDownList for one column which has a list of values to select.
I need to select a value and click on the Update button to update the database with the latest selected value.

String value = ddlprice.SelectedValue;
string MinutesSpent = (GrdAttributesView.Rows[e.RowIndex].FindControl("CmbMinutesSpent") as DropDownList).SelectedItem.Value;
}
Ideally in the RowUpdating method I should get the new value from the DropDown. but I don't understand why it gives the old value even though I select a different value.
I did a lot of reading and I saw different people using the same approach to get it done. But somehow it is not working for me.
Can someone help please?
I have a GridView that binds values from the database.
Here is the code:
<asp:GridView ID="GridView1" AutoGenerateColumns="False" DataKeyNames="DataView" runat="server" OnRowCommand="GridView1_RowCommand">
<Columns>
<asp:BoundField DataField="ProductName" HeaderText="Title" />
<asp:ImageField DataImageUrlField="ProductId" DataImageUrlFormatString="getProductImage.ashx?ProductID={0}" HeaderText="Image">
</asp:ImageField>
<asp:BoundField DataField="ProductDescription" HeaderText="Description" />
<asp:BoundField DataField="ProductCost" HeaderText="Cost" />
<asp:TemplateField HeaderText="Quantity">
<ItemTemplate>
<asp:TextBox runat="server" TextMode="Number" ID="txtQuantity"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
<asp:ButtonField Text="Button" CommandName="AddToCart" />
</Columns>
</asp:GridView>
I want to pass the command arguments containing values from txtQuantity and ProductID to the code behind on CommandName "AddToCart".
How can I do this?
Bind the values of the ProductID & Quantity in the GridView. In GridView, give like this:
<asp:GridView ID="GridView1" AutoGenerateColumns="False" DataKeyNames="DataView" runat="server" OnRowCommand="GridView1_RowCommand">
<Columns>
<asp:BoundField DataField="ProductName" HeaderText="Title" />
<asp:ImageField DataImageUrlField="ProductId" DataImageUrlFormatString="getProductImage.ashx?ProductID={0}" HeaderText="Image">
</asp:ImageField>
<asp:BoundField DataField="ProductDescription" HeaderText="Description" />
<asp:BoundField DataField="ProductCost" HeaderText="Cost" />
<asp:TemplateField HeaderText="Quantity">
<ItemTemplate>
<asp:TextBox runat="server" TextMode="Number" ID="txtQuantity" Text="<%# Bind("Quantity")%>"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
<asp:Button Text="Button" CommandName="AddToCart" CommandArgument="<%# Eval("Quantity") + "," + Eval("ProductID")%>" />
</Columns>
</asp:GridView>
In GridView RowCommand event, give the below code:
if(e.CommandName == "AddToCart")
{
string[] args = e.CommandArgument.ToString().Split(",");
Decimal Quantity = Convert.ToDecimal(args[0]);
int ProductID = Convert.ToInt32(args[1]);
}
I have a gridView which works nicely until I open a new window by clicking a button. When the new window is opened the values in one of the columns 'lblTotalPrice' gets erased. 'lblTotalPrice' is a template field, which is calculated in MealList_RowDataBound (quantity * price). The footer for the column, however is not affected when the new window is opened (also gets its value in MealList_RowDataBound).
Also the font-size of the data-bound columns are changed when the new window is opened.
Any ideas of what might cause this? When stepping through the code there are no other lines executed after btnEnvComment_Click
When gridView is databound again, everything is back to normal.
The gridView:
<rwg:BulkEditGridView ID="MealList" runat="server" AutoGenerateColumns="False" ShowFooter="True" GridLines="Vertical" CellPadding="4"

</ItemTemplate>
</asp:TemplateField>
</Columns>
<FooterStyle CssClass="MealListFooter" />
<HeaderStyle CssClass="MealListHead" />
</rwg:BulkEditGridView>
The code for the button that open the new window:
protected void btnEnvComment_Click(object sender, EventArgs e)
{
int offsetPos = 125; // set placement of new window
String URL = "EnvComment.aspx?MealID=" + Session["MealId"];
String responsCommand = "window.open('" + URL + "','_blank','height=400,width=300,top=" + ",left=" + offsetPos.ToString() + offsetPos.ToString() + ",titlebar=1')";
Response.Write("<script>");
Response.Write(responsCommand);
Response.Write("</script>");
}
i'm using a GridView and trying to sort and page it.
I have more than 20 rows on my DataBase, but the GridView just shows 10.
I set AllowPaging=true but noting happened.
Also I'm using AllowSorting = true and OnSorting="GridView_Sorting". But when I click on the header to sort the the content of that column, it does not enters on my OnSorting="GridView_Sorting" it goes right to the GridView1_RowCommand why ?
Sometimes it just give me this error:

Add SortExpression attribute for each sortable column, informing its DataField.

}
Hope this helps.
First of all, if you want to show the Name of sender and not ID, you have to modify your query to join in the table that contains the name
For date issue, you can use Format(Date, "dd/mm/yyyy")
Can you ensure that your query actually returns all the characters before binding to the grid?
