Forms Data Controls :: Dynamically Created TextBox In GridView Does Not Show Updated Value After Postback?
May 10, 2010I have a grid view that is dynamically created.In which every cell in the girdview has a 2 textbox (cTxtboxQty,ctxtWorkOrder) and 2 label.
When user click on the cell, a pop up come out and user are able to change the text inside the cell and click save.After that the pop up close and changed data immediately reflected on the screen.
My problem is:
After my data are changed and updated to database on the pop up page and having it post back to the parent page , my dynamically created textbox in gridview retain old value even new value has been assigned to it.
This sound very weird but i have no idea how to solve this.
My client side code is as below :

Forms Data Controls :: DataList - Updates Show Original Values Not Updated Values?
Jun 3, 2010Updates to the edited item are not passing the new / updated values but rather the original values. And I can't for the life of me figure out why when I change the original value in an edit textbox and post the update the new value is not being passed. I get the original value. Perhaps fresh eyes can spot the problem. This should be super basic but apparently I'm missing something.
Here's the code for the Item and Edit templates. The code behind is below this.

View 6 RepliesForms Data Controls :: How To Get Row Index From GridView After A Cell Is Updated
May 5, 2010I have a simple grid with 5 columns. The first 4 are numeric values I have formatted with templates. The last column is a total and I've added the Update button on the end. When the Update button is pressed, I have it updating the table with the new values and calculating the Total column. My goal is to have the Total column calculated after each cell is updated and not when the Update button is pressed.
I've added CommandName="myUpdateRowTotal" to
my templates.
<ItemTemplate>
<asp:TextBox ID="R01_Item_txt" CommandName="myUpdateRowTotal" runat="server" BackColor="White"
Font-Names="Arial" Font-Size="10pt" ForeColor="Blue"
Text='<%# Bind("R01_TARGET_COMMISSION", "{0:###,###,##0}") %>'
Width="75px"></asp:TextBox>
</ItemTemplate>
Forms Data Controls :: >>>Unable To See Updated Record In Gridview<<<?
Sep 23, 2010There is a very common problem I am facing in my new webproject in gridview control.The sequence of the execution of the process is as follows:There are some search parameters in SearchPage with a gridview. In gridview's rows there is an Edit button.By providing search parameter(s), data populated to gridview and if we click edit button a new page opens as a popup to update record.In new page the record is updated fine. On successful updation user close the window but he goes to the Search page he again finds the same record with the same parameters to see changes it remains unchanged.Its only changed when he search another record and then again provides the previous parameters.I don't know why is this behaviour of gridview?
Any idea would be helpful.

Forms Data Controls :: Unable To Capture The Updated Value Of Texbox Within Gridview: TextBox TextNewQuantity = (TextBox)
Feb 4, 2010I have been trying to achieve the following:
1-Allow the user to change the quantity in a textbox i.e // "txtQuantity"
2-capture the newly entered quantity i.e //int integerNewQuantity= int.Parse(textNewQuantity.Text);
3-update the database using the newly entered quantity i.e. //UpdateItem(data,integerNewQuantity)
Problem:1-I have not been able to capture the text i.e. the newly entered quantity i.e. the value entered in the text box "txtQuantity"
2-Hence the database is updated using the existing value and NOT the new value unless I make a constant assignment as below:
textNewQuantity.Text = "2"; When tested the assignment of any number correctly updates the database. see the c# code:
C# code: Version.1
