Repeater Template Sub - Control Visibility Before Databind
Jul 1, 2010
I have a custom control which contains a Repeater control. The Repeater has an ItemTemplate. Inside that item template I have a panel which is going to hide something based on "IsEditable" a boolean property of the custom control. What I would like to do is set the panel's visibility once before the Repeater is databound.
I know I could do an onItemDataBound event and use FindControl to get the panel but that seems a little excessive since it will always be either visible or not for all rows and I have no other actions that need to occur on databind. Is there a way to find the control in the ItemTemplate before the Repeater is databound?

I have a Custom Repeater control that inherits from Repeater and has paging functionality, however when I click the next page button the first time it refreshes the control but does not change the page, if I click it again after that it changes page perfectly. I know what the issue is, when I click the next button it does a postback, then the data is bound to the repeater, and then after that the NextButton Event is handled.
Is there any way I can change the order of the page load events?? Or force the repeater to reload again after the event is handled?? I've included my Custom Repeater class bellow:
using System.Web.UI.WebControls;
using System.Web.UI;
using System.Data;
using System.Collections;
using System;
namespace ASPresentation.Controls
{
[ToolboxData("<cc:PagedRepeater runat=server></cc:PagedRepeater>")]
public class PagedRepeater : Repeater
{
public int PageSize { get; set; }
public int CurrentPageIndex
{
get
{
return Convert.ToInt16(Page.Session["ProjectIndex"]);
}
set
{
Page.Session.Add("ProjectIndex", value);
}
}
public PagedDataSource pagedData = new PagedDataSource();
LinkButton NextBtn = new LinkButton();
LinkButton PrevBtn = new LinkButton();
public bool IsLastPage
{
get
{
return pagedData.IsLastPage;
}
}
public bool IsFirstPage
{
get
{
return pagedData.IsFirstPage;
}
}
public override object DataSource
{
get
{
return base.DataSource;
}
set
{
pagedData.DataSource = (IEnumerable)value;
}
}
protected void NextButtonClick(object sender, EventArgs e)
{
if (!IsLastPage)
{
CurrentPageIndex++;
}
}
protected void PrevButtonClick(object sender, EventArgs e)
{
if (!IsFirstPage)
{
CurrentPageIndex--;
}
}
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
NextBtn.Text = "Next";
PrevBtn.Text = "Prev";
NextBtn.Click += new EventHandler(NextButtonClick);
PrevBtn.Click += new EventHandler(PrevButtonClick);
}
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
base.Controls.Add(PrevBtn);
base.Controls.Add(NextBtn);
}
protected override void Render(HtmlTextWriter writer)
{
base.Render(writer);
}
public override void DataBind()
{
pagedData.AllowPaging = true;
pagedData.PageSize = PageSize;
pagedData.CurrentPageIndex = CurrentPageIndex;
base.DataSource = pagedData;
base.DataBind();
}
}
}

Here is a perplexing issue I have not seen a good answer to on StackOverflow, although there a couple stabs at it... I have a situation where I'd like to do this:
<asp:Repeater ID="MyRepeater" runat="server" OnItemDataBound="MyRepeater_ItemDataBound">
<ItemTemplate>
<li id="id?">
All the other stuff
</li>
</ItemTemplate>
</asp:Repeater>
is how do I get the ID of my <li> elements to be id1, id2, id3, etc., based on the ItemIndex they are bound to? So far the most... er..."elegant" solution I've come up with is to replace the <li> with an asp:Literal and dump the <li...>' text. But that just feels... so wrong. And no, I'm not using ASP.NET 4.0, which I've read will provide this functionality.

I'm having trouble managing how to call upon databind from clicking on a row over an already populated repeater that will populate data regarding the row clicked TO another repeater on the same page.
I've succeeded doing that with postback, calling a jquery click event of that row, taking the data of the specific row and passing it onto a "Querystring" and after postpack, it will be pushed into a Session which the ObjectDataSource of the secondary repeater will recognize and populate the data tables accordingly.
The problem is, I must do it without a postback or in other words purely on client side.

I have sub classed a asp repeater similar to A Grouping Repeater All works fine apart from if I also have a <HeaderTemplate> </HeaderTemplate> The grouping template is rendered before the header template. I would really like to either be able to choose the order in which the templates are rendered or just have the <GroupTemplate> Rendered after the header.

aspects of some controls in Code Behind (VB) with controls inside a datalist and/or repeater. I have read a lot of stuff on using some tricks but none seem to work so far. I am new to ASP.net so some of the explanations are too cryptic as well. Below is a section of code that I am trying to change. This example is attempting to make the label visible if the dataitem is true and hidden if false. No matter what I seem to do I cann't reference this label to change. I also want to change the text on some other controls in this dataitem if the returned value is a certain value.

I am using a repater whose item template is having a dropdownlist. Now i want to access that dropdownlist from a button click event. Here is the code iam using :
protected void btn1_Click(object sender, EventArgs e)
{
foreach (RepeaterItem item in rptWord.Items)
{
DropDownList ddl1 = (System.Web.UI.WebControls.DropDownList)rptWord.FindControl("ddlWord");
}
}
But m getting ddl1 as null. For this i created a function which is as follows:
public void myFunction(object sender, RepeaterItemEventArgs e)
{
foreach (RepeaterItem item in rptWord.Items)
{
DropDownList la = (System.Web.UI.WebControls.DropDownList)e.Item.FindControl("ddlWord");
}
}
using this function iam able to access the repeater but i guess its not possible to call this function on button click event .

My Gridview is refreshing its datasource when the edit button is clicked. How can I prevent this from happening? This isn't much of a problem when there aren't a lot of records, but when there are many it takes awhile. The data is already loaded so the edit button shouldn't need to reload the data. The edit button is a template edit button, and I'm using an SQL Datasource that connects to an Oracle database. The SQL datasource uses a control parameter that points to a dropdownlist.

I have worked a lot with gridviews, etc, but I am relatively new to Repeaters and I have a page that uses a Repeater to display records from a SQL Database. By default the date in the SQL field is 01/01/1900. I need to format the dateSHAWSTART & dateSHAWEND in my repeater so that if the date is 01/01/1900 that the fields should be blank. Here is my VB Code Behind:

I have a repeater which does quite expensive processing when it is populated. It gets the info from a web service which is itself a federated search service and will take 15 to 20 seconds to return results.
In each repeater item/alternatingitem, i have 3 imagebuttons doing some actions (saving in session some ID's, updating some custom collections...) , the problem is when clicking on one of the buttons, the repeater will trigger the command and then databind again, which takes quite some time to process again..

Here is the situation I have, I have a repeater inside a Usercontrol. The datasource is a IEnumerable<Investor> Exposed through a UserControl's Property. I have overridden the UserControl's databind event to set the Repeater Datasource before databinding the repeater. When it's not a postback, it databinds find and the events on the repeater item's controls fires up fine. But there is one event on repeater items (Delete Investor) which call back the DataBind of the UserControl after removing the Investor from de datasource. When this Event is called, it does all the work (deleting the investor and so on...) calls back the usercontrol's databind but when (within the usercontrol databind) the repeater is databinded again, the repeater items doesn't update (repeater items for investor not on the DataSource anymore still appears). My ItemDataBind doesn't even fire by then.

I have a main menu option of "Dashboard". Under this menu item I have 2 options: 1) Campaign Manager & 2) Negotiation Manager. Now, what is interesting is when I am in either the campaigns role OR the auto-negotiation role I see the Dashboard and BOTH sub-menu items. This is not the behavior I expected. I expect to only see both sub-menus when I am in the campaigns role AND auto-negotiation role. The OR scenario should give me the Dashboard menu item and one OR the other sub-item...Am I doing something wrong here or thinking a wrong way?

I have a gridview and I have to control the visiblitiy of the grid columns using javascript. Consider this gridview. I have a few columns.
<asp:GridView ID="grdTest" runat="server" AutoGenerateColumns="False" Width="100%">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="chkResource" runat="server" />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Resource">
<ItemTemplate>
<asp:Label ID="Resource" Text='<%# Bind("Resource") %>' runat="server" />
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="Description" HeaderText="Resource Description" HtmlEncode="false">
<ItemStyle HorizontalAlign="Center" />
<HeaderStyle HorizontalAlign="Center" />
</asp:BoundField>
</asp:TemplateField>
</Columns>
</asp:GridView>
I can control the visibility of these columns at the server side by using this -
grdTest.Columns[n].Visible = false;
But, I have to control the visibility from the client side using javascript. I tried a lot but I was only able to access either the row object or any particular cell of the gridview.
grid.rows[index].cells[i].style="display: none"; //for cell
Is there a way to access the column object of the gridview and control its visibility using javascript?

I want to change controls visibility on c#, but nothing happens. The controls are in an AspxPopupControl and 3 of them are hidden in design time, 1 of them is visible. I use this code to visible them
if (paramType == "Grup")
{
gv_Answers.Visible = false;
trlGroup.Visible = true;
chkShowItems.Visible = true;
}
else
{
gv_Answers.Visible = true;
trlGroup.Visible = false;
chkShowItems.Visible = false;
}
This code is in a CustomCallBack event of a gridview. So i don't know what to do from this point. It's an easy task but i couldn't handle it.

I'm displaying summary and details customer info in each repeater row - inside the repeater .
The summary stuff is it's own div: (id="divHistory_Summary). The details stuff in it's own div:
(id="divHistory_details" )
The details div is hidden by default with inline style: display: none;
[code]....
I don't have the jquery.js file in the head of my app, so I hope it's ok to call the script right here. This app has many nested master pages, and didn't know which one to put the call to jquery file.
The page loads, repeater populates, the details stuff is hidden. When clicking the summary div, nothing happens - the details stuff won't show.

I want to change the visibility of two asp.net image controls (runat="server") at the beginning and the end of the method call duration. I mean, I want the first image displayed and second one remains hidden until the last line of my method, which in turn, the second image becomes visible and the first one hides. I've put the area of the triggering control in updatepanel and have declared triggers of the updatepanel; But when I press the control (which is a button), the image at the end of the process is displayed correctly and on time but the one which should be displayed in the first line of the method is not displayed. I've configured my updatepanel to use conditional update mode and have used these lines for my intention:
imgLoading.Visible = true;
..
rest of the process
..
if (true)
{
imgLoading.Visible = false;
imgSuccess.Visible = true;
}
