this is driving me crazy.
I have a User Control that works right. On one of it's click events, I call (Label)this.Parent.FindControl("lblRequestNumber"); and it works ok, returning the label that I want. However I have another user control that needs to access the same label. This user control renders inside of one of the columns of a gridview inside the same parent page. This time, (Label)this.Parent.FindControl("lblRequestNumber"); returns null.
Why?? How can I access controls of the parent page, from a user control within a gridview row??
I found the solution. I needed to call "parent" a couple of times in order to get out of the GridView and find the control inside the parent page.
Using the Details Master pattern. When the form initially loads it shows a grid. When clicking on the grid the details are displayed, and is working perfectly fine. The issue with this design pattern is the first record is always loaded so when I look at the cursor the first record is showing.
I'm populating a two list view controls through code (one is available items and the second is selected with buttons to move the items back and forth between the controls) and my issue is when I press "New" the detail page is displayed but the list view is populated for the first record selected. I need a way to know when "New" is pressed I can clear out the list view selected control and just populate the available values.
I ended going a different direction and creating my own "New" button that calls a menu item to call a new form as a popup similar to how the form when entering a new customer works. Then I turned off the "New" button and now my code works fine without have to deal with the one screen containing both forms logic.
I have a userControl in which I load three different user control as Left,right and middle panel.
My middle panel user control have 3 more user control loaded on it
I want to pass a value from my middle panel user control to right panel user control on click of a link button.
Can please any one guide how to do so.?
I would add a method on the user control you need to pass data to.
Then you can call that method from the container and pass in the value.
Another approach is to put the value in session or viewstate.
Using Session or cookie this is easy way to pass value one control to another control or one page to another page
I am having a asp.net web page on which I am loading a single usercontrol (UC) ten times. The first user control will be used to gather data about the main employee and the rest about his dependent. There will be "next" and "Previous" navigation button to move from one UC to another. I have couple of DevExpress check boxes on the UC. If the user checks any of them on the first page and then clicks the "next" button to navigate to the next UC, I want the checkboxes in the dependent UC also checked. I tried to do that in the page load event of the dependent controls in code behind. The code is given below. But it doesn't work. Looks like that I have to use javascript to do it. Please let me know how to do it.
codebehind:
dependentCheckbox.checked = mainEmployeeCheckbox.checked;
Thanks
In a ASP.NET application I have a paging RadGrid which shows up textbox in each row. Outside the grid, there is an OK button to save the content of all the textbox. If user changes text in any one or more of the textbox and without clicking on the "OK" button, tries to move to a different page number (of the grid by clicking on the page number), he should be prompted for confirmation of save or cancel the changes.
I am guessing that one can write a Javascript function which would look for any form input control (textbox in my case) and detect changes and If there are changes, would prompt the user. However, I am not sure where I can call this function from? Any suggestion on this or a better way to achieve this would be appreciated.
I am using RadGrid but I guess this should be applicable to GridView as well.
I am not sure if this will help exactly but it might at least give you an idea:http://www.codeproject.com/KB/ajax/ajaxdirtypanelextender.aspx
