View 10 RepliesI am using the cascading dropdownlist controls from the Ajax toolkit. I have everything working perfectly and all of my select changes work. I have 3 related select boxes that all work great for single item select. What I need is for my last dropdownlist to allow for the selection of multiple items. I have tried adding the 'multiple' attribute to the final dropdown list and it allows the selection of multiple items but I cannot get the items when I post back, just a single item.
View 7 RepliesI have a list box that I want to allow the users to select up to 4 items from. I set the selection property to multiple, but for the life of me it won't allow multiple selection. If I pre-select 4 items, they show up as all selected when the page loads, but as soon as I select another, it clears all of them and then only allows one at a time. if I check the source code for the page, the property is set to multiple (see below).
HTML Code:
<td colspan="2" style="height: 28px">
<select size="4" name="MonthsListBox" multiple="multiple" id="MonthsListBox">
<option value="Jan">Jan</option>
<option value="Feb">Feb</option>
<option value="Mar">Mar</option>
<option value="Apr">Apr</option>
<option value="May">May</option>
<option value="June">June</option>
</select></td>

I am binding a checkboxlist with a dataset (with these columns :
id,empname,resourceId,balanceId as columns) with datavaluefield as id and datatextfield as empname;

1. "User should be allowed to check only say 5 items with same resourceId" using javascript
2. And in total he should select only 20 items (max 5 items for same resource id and max 15 items for the remaining)
How can we control this?

View 1 RepliesI was able to gather a value from a gridview based on a selected checkbox. However, I would like to be able to grab multiple values instead of just one. I tried using a for loop to gather my information and populate labels as a test. However, that caused an error. This is the code I currently have to use.
foreach (GridViewRow gvr in GridView1.Rows)
{
if (((CheckBox)gvr.FindControl("CheckBox1")).Checked)
{
lblTest.Text = gvr.Cells[1].Text;
}
}
How to gather multiple values and populate other labels? the other labels are labeled accordingly as lblTest2 and lblTest3. I currently am gathering my data from a gridview and only want to pull the StaffID from gvr.Cells[1].text.

I have a simple javascipt which enables/disables some checkboxes when another checkbox ticked/unticked. This works fine, however, in some instances when by page is loaded my code behind disables the same check boxes. When this happenes my original check box nolonger seems to have any influence in enableing or disabling - there is no error and all the elements seem to be found by the javascript - it just doesn't enable/disable the checkboxes.
View 5 RepliesIs there anyway to disable a textBox's validation(RequiredFieldValidator) base on the selection of dropDownList ?
View 5 RepliesI have 2 RequiredFieldValidator

I am absoluetly confused. My web app has a checkbox list that my code is looking to see if the user checked it. Like I said, very simple stuff... Here's the code:
If (chkLaunch.Items(1).Selected) Then
Launch = 1
End If
The odd thing is that when it gets to this bit of code it just moves right past it like it wasn't checked. The same thing happens when I use a single checkbox (rather than a checkbox list). I've tried a bunch of different ways to make the code work but I'm left to the conclusion that I'm just not telling it to do this correctly. Either that or my project is messed up somehow.I say that my project is messed up because when I add an object to the page in Design mode, it doesn't write the source code. So when I save and close, all the modifications are mysteriously gone. This happens on multiple PC's...So, is the checkbox problem just me not doing something correctly or is my web project messed up?
