Web Forms :: Hide Filter Control Dynamically?
Dec 22, 2010
I am using a filter control which contains two CheckBoxList controls (Country CheckBoxList and Region CheckBoxList) each residing in an UpdatePanel.
The functionality of this is...
Country Checkboxlist displays countries ( connected to database). Lets say two countries are there 1. Egypt 2. Russia
If user selects only one country, then I need to display Region CheckBoxList populated with regions.
If user selects both or none, then I should hide the Region CheckBoxList control.
I am using OnSelectedIndexChanged event.
The below is the code for OnSelectedIndexChanged event:
protected void Country_OnCheckedItemChange(object sender, EventArgs e)
{
PopulateRegion();
}
private void PopulateRegion()
{
[Code]....

I have a dynamically created grid view in the load even of my web page. I am setting its data source at run time like
gv.datasource = someObject.getItems();
gv.dataBind();
Now I wanted to hide, that is to make some of the columns visible false.
First how can I do that, Second should I write the code in the same page_load event or I should write the code some where else, cause when I add this line of code
gv.colums[0].visible=false;
an exception is produces "Argument out of range"

http://forums.asp.net/t/1576428.aspxIf any one of the As or Bs is populated, I need to hide the other one. So I enter something in A1, hide A2, enter something in B2, hide B1.I thought I could use a javascript OnBlur event to do this but it doesn't do anything unfortunately. I'm trying to get the fields to appear/disappear without having to do a postback.

I have a <asp:Wizard> control with 6 or so steps. In the first 3 steps, I want to hide the default Wizard navigation (Next button, etc.), as each WizardStep's contents will handle that. For the last 3 or so steps, if possible, I want to use the built-in navigation. I've modified the <StepNavigationTemplate> contents, but that alone doesn't cut it, because it affects all steps. Here are my options:
Find a way to dynamically show or hide the StepNavigation from the codebehind. (I feel like this might be best -- is it possible?)
Use StepType with <StartNavigationTemplate>, <StepNavigationTemplate>, and <FinishNavigationTemplate> to switch between navigation options (marking multiple steps as "start" or "finish" feels like it's abusing the mechanism)
Switch to a <asp:MultiView> and handle navigation manually (I'd rather not do this)

I would like to simply have an image button on my page that would show an image that says something like "Upload File".When the user clicks the button I would like for it to automate popping up the "select file dialog" exactly like the "browse" button does on the FileUpload control now. Then if the user selects a file and click "OK" I want to do a post back where I can then initiate the upload. If the user clicks cancel from the dialog I would do nothing.So all I am trying to do her is make it so that the user does not see the text box for the file name and replace the plain old browse button with an image and do a postback if they click ok from the dialog.

I am using Visual Studio 2005. I have a gridview and when it is in edit mode, there is a locked textbox and an associated dropdownlist for the signature field. If a name already exists in the database, it will show up in the textbox. In that case, I would like to hide the dropdownlist.
So far, I have not been able to figure out how to make this happen.
My latest attempt is this:
Protected Sub GridView1_RowEditing(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewEditEventArgs) Handles GridView1.RowEditing meString = (CType(GridView1.Rows(e.NewEditIndex).Cells(2).FindControl("meSigLabel"), Label)).Text Dim meDDL As DropDownList = CType(GridView1.Rows(e.NewEditIndex).Cells(2).FindControl("edMESigDropDownList"), DropDownList) If meString <> String.Empty Then meDDL.Visible = False Else meDDL.Visible = True End If End SubI receive a NullReferenceError. During debugging, the mestring variable has a value but the meDDL is Nothing.What am I doing wrong?

In securing actions/controllers, do I have to create a custom filter or use MVC built-in filter?
To use the built-in attribute Authorize() on an action/controller or create a separate class that inherits the ActionFilterAttribute which has a method (OnActionExecuting) to override and do the authentication there?

I have a master page (frame.Master) and a content page (default.aspx) that uses frame.Master. Within frame.Master I have an ASP Panel control (pnlQuote). I do not want pnlQuote within frame.Master to be visiable when default.aspx loads. Normally I use the following code within Page_Load of the default.aspx.cs page: this.pnlQuote.Visible = false; however this does not work because pnlQuote is within frame.Master.
correct code to hide pnlQuote within frame.Master when default.aspx is loaded?

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?

In my organization we use nested groups. For a particular usage, we have a group (let's assume that the group name "kuku"), and the names of all the nested groups under it contains "kuku" as well.
We may assume that no other group in the LDAP has "kuku" in the name.
I need to create a filter which will return all the users which belong to one of the "kuku"s group.
Obviously, using this filter will bring only the head kukus
(&(&(objectclass=user)(objectclass=person))(memberOf=CN=kuku,cn=...rest of the group DN...))
How can I use wild card to fetch all users which belong to any kuku?
For example: (&(&(objectclass=user)(objectclass=person))(memberOf=CN=.*kuku.*))
