I need to be able to set a textbox's (which is inside a gridview row) text to a certain string in runtime. I have used FindControl before, but can't figure out the syntax for actually setting the value of the textbox rather than just getting. Here's what I have, which doesn't compile:
((TextBox)e.Row.FindControl("txtPath")).Text = dataMap.GetString("targetPath"));
I know now normally you can get the value of a text input using the following:
txtName.Text
But because my input is inside of a LoginView I am using FindControl like this:
LoginView1.FindControl("txtComment")
This successfully find the text input but returns its type rather than the value. Adding the Text function at the end does not work.
my web application i use FindControl to retrieve a Control By Name (it returns an System.Web.UI object). The control can be of various type and I don't want to treat them differently: I'd like to set the Text property to a defined string. I hope there's a class that I may use to cast the control and set the Text property.

View 2 Replies My problem is as follows. I have a custom GridView control where I generate the Template fields for each column. I'm using someone elses class that extends the Itemplate and returns lables for ItemTemplate, and TextBoxes for EditTemplate.
I need this in order to implement bulk edit for the gridview where users press button Edit and all fields become textboxes, they can then change the values, and click Update button at which point I need to be able to retrieve the values from the TextBoxes in these Template Fields.
What I have tried thus far: when user clicks Edit button, my dynamic code builds the columns and specifies that the Template field is an EditTemplate, it then adds these columns to the grid view. The gridview shows the textboxes with all values retrieved from sqldatasource.
When I press the Update button, the page does a postback, as I can see Page_Load event fire, I check for a flag that I previously set when the Edit button was pressed (I store it's value in View State) and call the Update method.
In it I iterate throught the gridview rows collection, check that the RowType of each row is DataRow and call GridView.UpdateRow(i, false), passing each rows index to the UpdateRow method.At this point I have tried everything I can to find the values stored in the textboxes, but I cannot find any of the textbox controls.
I've tried using the current row's FindControl method and specifying the name of the textbox field,I've tried using Request.Params method where I can tried passing the client id, as it seen in the View Source of the page such as this
Request.Params["grid1$gvData$ctl02$MMCODE"]
Still no luck, I've tried going up an down the Row's cells, controls collections, it seem to list the counts for rows correctly, the same goes for the amount of cells for each row, but at no point was I able to actually locate any controls such as textboxes or anything else and retrieve any values from them.
I have an asp:table control that I construct dynamically. I place a few textboxes in it within a for loop and assign their IDs in code. I'll include an abbreviated code fragment showing how I'm doing this:
[Code]....
The page then displays correctly and the ID is set correctly when I view the source, but when I try to access the textbox later when the form is submitted the call to FindControl(idStr) returns null no matter what I do.
In my GridView I use FindControl/<FooterTemplate> with a TextBox that you can enter an integer with a comma
into the TextBox, because I create an instance of the Textbox first and then remove the comma out of the integer before the TextBox is used to update the table in the database.
However once the data is in the table and displayed in the GridView if you try to change the integer and use a comma in the GridView you cannot because FindControl/<EditItemTemplate> will not create an instance for you to remove the comma from the integer before it updates the table because FindControl/<EditItemTemplate> doesn't allow you to create an instance of the TextBox first, instead when you try to use the instance that looks like was created it gives an error stating:
Object reference not set to an instance of an object.
So the question is:
HOw do you create an instance of a TextBox in a GridView when using FindControl/<EditItemTemplate>?
<form id="form1" runat="server">
<div>
</div>
<asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">

I have what I think is a weird issue. I send text from one page to another via Session Variable. When page 2 loads, the text box has the session text set, but if the user changes the text and clicks the button, the SQL database is update with the original session text. If I remove the redirect from the page 2 button_Click method, then, the page refreshes with the textbox reverting to the session text and thr SQLDataSource has the session text added to it.

I have a page with a text box, a button and a GridView. Enter an account number in the text box, press the check button and the result will show in the GridView.
Now user wants that if the text box is clear, the GridView disappear.
I can only find TextBox1_OnTextChanged. But I want to have that while the user is clearing the text, if the length of text becomes zero, the GridView is clear out. So I am looking for OnTextChanging(). Well of course this function does not exist. How to achieve the same purpose?
I have an asp page with a textboxes, labels and other controls. I cannot get the .text to change in any of these controls. I click on button which I execute code that I expect to update the text but it doesn't work. Something like Textbox1.text = "Hello" Are there page level properties/settings I should look at? I am perplexed an looking for a place to start. I will provide more information as needed. I just don't know where to start.
