I am trying to find a child control from a repeater control's child control. I have the following structure like a top control is a repeater, below which is a Panel and below this is a DateControl(custom control).
I have an imagebutton control in the column HeaderTemplate of a gridview and want to know how to reference the imagebutton so I can add an attribute to it programmatically. Following is the code for my gridview control:
[Code]....
I can reference the checkbox control correctly with CheckBox chkbox = GridView1.FindControl("chkSelected") as CheckBox;However, I have tried the following code for the imagebutton but I get the error message Object reference not set to an instance of an object.:
[Code]....
Or is the OnInit event handler the right place to reference the control?
Inside repeater control HeaderTemplate i have some LinkButtons and Checkbox I want to findout the object (Linkbutton or checkbox) that raises the event.
[Code]....
When i write such code i received error as A switch expression or case label must be a bool, char, string, integral, enum, or corresponding nullable type
I am using an event calendar control (not a MS control) and I am trying to access a LinkButton inside this control's HeaderTemplate. Below is what I have tried so far. I get the familiar "Object reference not set to an instance of an object" error. Does anyone has an alternate way to get this control? I need to change the visibility property of it.
I'm trying to write a bit of code that will format all the numeric values in lables in my gridview. here's what i am doing right now:On the RowDataBound Event, i create a row object for the row that is currently being bound.then i go use the FindControl method to grab each label by name.Problem is there's too many columns in this table and i really dont wnat to have to type it all out. Here's an example of what i am currently doing
[Code]....
Can i use myRow.Controls to grab a list of all the controls and then somehow get a list of all labels in the collection and then use a for loop to go through and format each label?
I am using a repeater control and i want to use one more repeater control inside the existing repeater control .Â
Like this:
<asp:Repeater ID="Repeater1" runat="server">   <HeaderTemplate> </HeaderTemplate>      <ItemTemplate> <!-- start child repeater -->    Here I want to use one repater control     <!-- end child repeater --> </ItemTemplate> </asp:Repeater>
Probably a fairly simple one. Just need to know how I can make reference to controls in the HeaderTemplate of a DataList. I've got a form in there that I need to get the data from.
I have a dropdownlist in a headertemplate but I can't seem to access it in the code behind to work with the onselectedindexchanged event. I want to change the data that is shown on the event but can't access the control.
I'm currently experiencing issues when I try to update the text value of a label. The label is located within a HeaderTemplate. The HeaderTemplate is within a Wizard control. why I'm uable to access it directly or with using findcontrol?
I believe that Findcontrol returns back a null when I go that route. Here's a code snippet below of what I'm working with. I'm trying to update lblCurrentJob with text that changes based on what the user selects on my page.
I cannot dig out the controls correctly in my code, as they are hidden in a datalist. I am trying to update some data into a row in the 'resume' table. Is INSERT INTO corrent for updating data which is already there?
and also i cannot find the controls in the datalist correctly....?
I need to access a control inside a repeater and change its properties. To enable it or not. I got an erorr message Object reference not set to an instance of an object. Here is my code inside a method. protected void
rptCAP_ItemDataBound(object sender, RepeaterItemEventArgs e) { LinkButton lnDel = (LinkButton)rptCap.FindControl("lnkDelete"); lnkDel.Enabled = false; //<<<<< this is where the error occur }
I have a nested accordion control for categories and sub-categories with a gridview to display the data. What I am trying to do is to hide the "Header Template" when sub-category is "Not Defined" but the results are usually inconsistent and seems like if i define HeaderCssClass, HeaderSelectedCssClass declaratively then it overrides the conditional css styles defined in code (c#) for OnItemDataBound event whereas if I don't define declaratively then css in code is not consistent.
I am not sure how to approach this or if I am using the correct event for this.
In the code - I used label's forecolor proprtery to match to the background as a workaround for now but not happy with it.
I can set lblSubHeaderId.Visible = false; which works consistently but then I still have this predefined HeaderCssClass, HeaderSelectedCssClass which is still shown as a placeholder/ just a horizantal line for the headers where lblSubHeaderId is set to false.
I have a gridview where I in codebehind add a templatefield
[Code]....
In my update command when i try to find the "Result" textbox I get a null object [Code]....
In the gridview there is another templatefield "Name" that consist of two boundfields("Firstname" and "Lastname") This column is added in the design phase and not in the codebehind.I don't have any trouble finding these controls using the ID added in the markup [Code]....My issue is with the result column that I add in codebehind.
