Unable To Access Dynamic Controls Inside Ascx Using Javascript On Aspx Page
Jun 2, 2010
I have a user control (ascx) which contains a control (hidden field). In the page_load event of ascx, i have the below code:
HyperLink.Attributes.Add("onclick", "JavaScript:return AccessControl('" + hdnField.UniqueID + "');");
Note: The hidden field resides in .ascx file.
I want to access this hidden field at runtime and i have the below javascript function in aspx page that loads the usercontrol.
function AccessControl(hdnFieldId)
{
var ctrl = document.getElementById(hdnFieldId);
alert(ctrl);
I am getting 'null' value in the alert. I tried using 'ClientID' and 'this' instead of 'UniqueId'. I am wondering why this is not working. I am using .net 2.0.

Using vb.net/asp.net 2005:
I am trying to access my accordian in my javascript so I can expand the first (and only) pane but whenever I do that I get a page error before the page loads "Object reference not set to an instance of an object'
The name of my accordian is "myAccordian". and the accordion is inside a gridview.
Just for testing I did the $find on my gridview (not the accordion) and that worked fine,

I have a requirement where I have a webpart and two ImageButtons(imgGV, imgLV) and a hidden input textbox('ctl00$MainHeaderContent$txtType') in an aspx page. I need to change templates to this Webpart either to show results in "Grid View" or as "List View" on the click of this ImageButtons. I added code in the page_load of .aspx page as
imgLV.Attributes.Add("onclick", "document.getElementById('ctl00$MainHeaderContent$txtType').value='LV';return true;");
imgGV.Attributes.Add("onclick", "document.getElementById(('ctl00$MainHeaderContent$txtType')).value='GV';return true;");
When I am clicking the specific ImageButton, it has to write into hidden field either "GV" or "LV". In the webpart CreateChildControls I assign templates based on the text in Hidden field either "GV" (Grid Template) else "LV" (List Template). In the CreateChildControls of Webpart for the template change, I am getting the Hidden value as empty. I am using coding as
HtmlInputHidden t = new HtmlInputHidden();
t = (HtmlInputHidden)this.Page.FindControl("ctl00$MainHeaderContent$txtType");
if (t.Value=="GV") {
assign one template}
else { another template}.
I am getting t.Value="". Question is: Is it like if we add some text in a hidden textbox using the Javascript function in an aspx page, the same textbox value in the same aspx page but in the Webpart class in the CreateChildControls method using the code as this(webpart).page.FindControl("Textbox").text is showing empty. So the text added using Javascript into Textbox is it not available in the code behind code using "Text" property of the same Textbox?.

I have two files in my project. One is user control (popup) customerpicker.ascx and one is default.aspx page. In customerpicker I have dynamically generated gridview and 'select' column with SelectButton.
What I want is this: When I click on 'select' on random row in gridview, then I like to display value from selected row immediately (like ajax) to aspx.page. How it is possible?
There is part of my code in .ascx:
public string showOnaspx { get; set; }
protected void GridView1_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)
{
GridViewRow row = GridView1.Rows[e.NewSelectedIndex];
showOnaspx = row.Cells[1].Text;
e.Cancel = true;
}
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
GridViewRow row = GridView1.SelectedRow;
//row[i].Attributes.Add("onclick", "$('#ContentIndex_sometextbox).val(" + row[i].Cells[1].Text// + "); $('#Close').click();");
}
I also tried with jqeury (comment in selectedindexchanged function), but it does not work well, because user have to click SELECT two times to effect.

I have a variable in an aspx file I need to use/recover it's value into an ascx web control that's in this aspx file. It's possible to do it? The aspx dynamically loads web controls depending the scenario, so this web control not allways is loaded.

I have a simple user control which is nothing but a simple input field with runat="server":
<input id="mySimpleTextBox" type="text" runat="server"/>
My observation so far in the output rendered by a datalist (when I use this user control inside it) is that the value for the name attribute is the same.I want to use this control inside a datalist/repeater such that I'd want a unique value for the input element's name attribute when the datalist/repeater renders. How is this done?
EDIT: My bad obversation. Actually the names are unique. However, when I try to post the page to another web page which outputs the key & value of all the items in Request.Form I don't see the input elements...

I've got an aspx page that renders an ascx page with filtering capabilities. Inside the ascx page, parameters are passed as follows:
<tr>
<td class="label">Plataforma</td>
<td class="field lookup"><%= Html.Lookup("s.Site", null, Url, "Sites") %></td>
</tr>
<tr>
<td class="label">Data</td>
<td class="field date"><%= Html.TextBox("s.Date", DateTime.Today.ToString("yyyy-MM-dd")) %></td>
</tr>
I need to be able to get those parameters on the main aspx page, because they are needed for an action that is called there. How could I access these parameters?

I have written a web usercontrol (ascx). Inside, there is a Panel that I want to show/hide on click of a hyperlink inside the usercontrol.
Normally, this is easy just by doing something like this (the onclick attribute is added to the hyperlink on prerender):
var PanelToShow = document.getElementById('<%=PanelInvoiceHasBeenCreated.ClientID %>');
if (PanelToHide != null) {
PanelToHide.style.display = 'none';
}
but because the ascx control is held within the gridview, the above will assess all the controls (of which there are many in the gridview) with the name 'PanelInvoiceHasBeenCreated'. The only time it will work is when there is 1 row in the gridview. Currently, with my existing code, if I click the hyperlink in any row, it shows/hides the panel in the bottom row of the gridview!
Therefore, my question is how do I get the actual, unique ID I need to show/hide on the correct control in the correct row?

I have a requirement like, There is a grid that has multiple rows. On clicking the "add to list" button, the columns from this grid is added to list of tables where source for one table in this list is read from grid view. note that, the grid view and tables will be having just two columns but the rows added to each table might vary.
I trying to implement this using GridView inside a gridview option but looking for some lighter way to implement this.

I have a button on a page with a Repeater and an ObjectDataSource. To give credit where credit is due, the Repeater's paging functionality is courtesy of ScottGu. (However, I'm using ASP.NET 4.0 and SQL Server 2008, as opposed to ASP.NET 2.0 and SQL Server 2005.)
Anyway, in the button's click event, I need to access the Text property of a Label that's inside the Repeater because it's used as an input parameter in a stored procedure. I'm getting a NullReferenceException when trying to access the Label's Text property. I have researched this error and have tried a few different solutions (involving FindControl and the Repeater's ItemDataBound event), but I haven't been able to get it to work. The code is below.
