I am trying to create dynamic controls on button click.
HTML:
<asp:LinkButton ID="lnkSrt" runat="server" Text="Multi Sort" ForeColor="Black" Font-Names="Calibri" Font-Size="10pt" />
<ajax:ModalPopupExtender runat="server" ID="mpeSrt"
TargetControlID="lnkSrt" PopupControlID="pnlSrt" CancelControlID="btnClose">
</ajax:ModalPopupExtender>
<asp:UpdatePanel ID="upPanel" runat="server">
<ContentTemplate>
<asp:Panel ID="pnlSort" runat="server" align="center" Style="display: none" BackColor="LightGray">
<asp:Label runat="server" Text="Sort By Column" />
<asp:DropDownList ID="ddlColumnSort" runat="server" AutoPostBack="true" />
<asp:Label runat="server" Text="Order By" />
<asp:DropDownList ID="ddlOrder" runat="server" AutoPostBack="true">
<asp:ListItem Text="Ascending" Value="0"></asp:ListItem>
<asp:ListItem Text="Descending" Value="1"></asp:ListItem>
</asp:DropDownList>
<asp:LinkButton ID="lnkAdd" runat="server" Text="Add Sorting" Font-Underline="true" OnClick="lnkAddOrder_Click" Font-Names="Calibri" Font-Size="10pt" ForeColor="Black" />
<asp:Button ID="btnSorting" runat="server" Text="Sort" OnClick="btnSorting_Click" />
<asp:Button ID="btnClose" runat="server" Text="Close" />
</asp:Panel>
</ContentTemplate>
</asp:UpdatePanel>
CODE:
When clicked on AddSorting I am trying to create dropdown control using below code and the controls doesn't show.
protected void lnkAddSort_Click(object sender, EventArgs e)
{
int index = pnlSort.Controls.OfType<DropDownList>().ToList().Count + 1;
this.Createddl("ddldyn" + index);
}
public void Createddl(string id)
{
DropDownList ddl = new DropDownList();
ddl.ID = id;
pnlSort.Controls.Add(ddl);
Literal lt = new Literal();
lt.Text = "<br />";
pnlSort.Controls.Add(lt);
}
Image:
pnlSrt is set to display: none so the dynamically added child controls will not show either.
As per the #Yoshi answer. You could set visible true for the pnlSrt control by using pnlSort.Style["display"] = "block";// or pnlSort.Attributes.Add("style", "display:block");
Try this
public void Createddl(string id)
{
DropDownList ddl = new DropDownList();
ddl.ID = id;
pnlSort.Controls.Add(ddl);
Literal lt = new Literal();
lt.Text = "<br />";
pnlSort.Controls.Add(lt);
pnlSort.Attributes.Add("style", "display:block");
}

Is there a way to set the ID for multiple radiobuttonlists generated via repeater.
ie. ID= rep1 rep2 rep3 rep4
I would like to be able to place my data in multiple columns across a table.
Heres is my code so far:
<asp:Content ID="BodyContent" ContentPlaceHolderID="MainContent" runat="server">
<h2><%: Title %></h2>
<h3>Your application description page.</h3>
<asp:Repeater ID="Repeater1" runat="server" DataSourceID="SqlDataSource1">
<ItemTemplate>
<asp:Label ID="lblQuestion" runat="server" Text='<%# Eval("Text") %>' />
<asp:RadioButtonList ID="ddlAnswer" runat="server" AutoPostBack="True" RepeatDirection="Horizontal">
<asp:ListItem Text="Yes" Value="True" />
<asp:ListItem Text="No" Value="False" />
</asp:RadioButtonList>
<asp:Panel ID="Panel1" runat="server">
<asp:Label ID="Label1" runat="server" Text="Provide more details:"></asp:Label>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</asp:Panel>
</p>
</ItemTemplate>
</asp:Repeater>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:DefaultConnection %>" SelectCommand="SELECT [Text] FROM [Questions]"></asp:SqlDataSource>
Behind:
protected void Page_Load(object sender, EventArgs e)
{
foreach (RepeaterItem item in Repeater1.Items)
{
RadioButtonList ddlAnswer = item.FindControl("ddlAnswer") as RadioButtonList;
System.Web.UI.WebControls.Panel Panel1 = item.FindControl("Panel1") as System.Web.UI.WebControls.Panel;
if (ddlAnswer.SelectedValue == "False")
{
Panel1.Visible = true;
}
else
{
Panel1.Visible = false;
}
}
}
You can just use ClientIdMode="Predictable" attribute in the aspx mark-up to assign different ids to different dropdownlists like this:
<asp:RadioButtonList ClientIDMode="Predictable" ID="ddlAnswer" runat="server" AutoPostBack="True" RepeatDirection="Horizontal"> ...
I have a ASP.NET ListView inside an UpdatePanel.
In the ItemTemplate there are 2 buttons with Commands "UpdateCart" & "RemoveCart".
In both the commands, the datasource of ListView (an SQL DataSource) gets rebound.
There is no InsertCommand/UpdateCommand/DeleteCommand on the SqlDataSource
My problem is :
Whenver these buttons are clicked : the datasource does not get refreshed.
however I can see from debug mode that values are indeed passed to the datasource selecting method correctly.
The relevant ASPX Page :

Try replace your buttons outside the updatepanel. Page will not getting refresh when the buttons are in updatepanel. sorry i can't make comment so I post here as an answer.
I have a large dataset binding to a gridview that is inside of a 300px height restricted DIV tag. When I select a row and trigger the edit function the page reloads the data (as desired) into the gridview and takes me back to the top regardless of how far I may have scrolled down.
Is there a way ideally only using asp.net c# to focus on the row that is being edited. I don't mind if this involves the row being placed at the top of the grid while in edit mode if that is required.

I'm creating web template using asp.net and C#.
in my user control page i have to create the table dynamically inside the list view. I just read the data from XML file then retrieve the name and number of columns and rows of each table. While I'm creating the table I assign the name and id to each cell. In this dynamic table once the user click on the edit button of each row all the cells of this row will change to textbox. then the user can change the data of this textboxes,
but in my update function I cannot access to these textboxes by id and store the data in database.
Below is my dynamic table code which is created at the ItemDataBound function:
System.Data.DataRowView rowView = e.Item.DataItem as System.Data.DataRowView;
TableRow tr_DataBound = new TableRow();
TableCell tc_DataBound = new TableCell();
for (int i = 1; i <= pkCounter + nonPkCounter; i++)
{
//tc_DataBound = new TableCell();
tc_DataBound = new TableCell();
TextBox tb = new TextBox();
//(TextBox)e.Item.FindControl("td_EditTemp" + i);
tb.Width = 110;
tb.Text = rowView[i - 1].ToString();
tb.ID = "td_EditTemp" + i;
tc_DataBound.Controls.Add(tb);
tc_DataBound.CssClass = "th_ItemTemplate";
tr_DataBound.Cells.Add(tc_DataBound);
}
tr_DataBound.Cells.Add(tc_DataBound);
Table table_Lv_ItemTemplate = (Table)e.Item.FindControl("Table_Lv_ItemTemplate");
table_Lv_ItemTemplate.Rows.Add(tr_DataBound);

I'm using below method in my update function at the code behind to access the data changed at the textbox:
TextBox tb = (lv_Uc_Module.Items[e].FindControl("td_EditTemp" + i + "_" + e)) as TextBox;
Could you please guide me how to access these textboxes data. Appreciate your consideration.
Have you looked at using the asp:repeater?
It makes creating dynamic controls much simpler especially if you use the 'Data_Bound' Event.
Have a look here - repeater example.
I have a GridView with a column of checkboxes (the rest of the GridView is being populated from a database). I'm using AJAX to perform different functions, and I'm wondering if i'm just not calling the OnCheckedChanged event in the right place. Should it be wrapped in some sort of UpdatePanel? I'm still really new to how all of this works...basically what I'm aiming for is to change a bit value in my database when a checkbox is checked. I know the logic of how to do that, I just don't know if I'm addressing my OnCheckedChanged event the right way.
.CS
protected void CheckBoxProcess_OnCheckedChanged(Object sender, EventArgs args)
{
CheckBox checkbox = (CheckBox)sender;
GridViewRow row = (GridViewRow)checkbox.NamingContainer;
OrderBrowser.Text += "CHANGED";

Try turning AutoPostBack on for the checkbox control.
<asp:CheckBox ID="CheckBoxProcess" runat="server" Enabled="true" OnCheckedChanged = "CheckBoxProcess_OnCheckedChanged" AutoPostBack="true" />
This maybe the reason your method isn't being called.
Please try to check the value with the DB:
Checked='<%# Convert.ToBoolean(Eval("Processed")) %>'
