View 6 RepliesI have one UpdatePanel which contains search criteria controls for a GridView.
The GridView is in another UpdatePanel.
I have a reset button in the search criteria UpdatPanel which resets all the search controls to their default values. However when I click this button for some reason my GridView RowDataBound method fires.
This is slowing the page down when the reset button is clicked. Does anyone know why this is happening and how to stop it. I haven't posted the code and explained it in plain english for ease of reading.
When a gridview is rendered, its RowCreated event is called. When it is called, what is contained in the second parameter which is of type System.Web.UI.WebControls.GridViewRowEventArgs ?Means, which type of information can we get from that ?

The 1st time I submit the form everything is working well, the second time theGridView1_RowCreated fires an exception when the property AssetClass is called. The error message isMust specify valid information for parsing in the string. This is becauserblAssetClass.SelectedValue is empty, but I don't uderstand why.

I have info from a couple of different tables that I need to be able to double click on a cell in a gridview and navigate to a couple of separate .aspx pages. Yesterday I learned how to use RowDataBound to get the name from a cell on a gridview to use in a delete confirmation dialoge box, and so am pretty sure I should be using this same RowDataBound, but I cant quite figure out where to start.
For example from the gridview below, I need to be able to double click in the "LoginIssue" field and navigate to an "EditLogin.aspx" page and subsequently be able to double click in the "ContractPath" and be able to navigate to a "ContractPath.aspx" page...or popup.

View 2 Replieswhen i add a rowdatabound event to a gridview, the pager disappears. when i remove

from gridview, pager comes back to life.
I have two different functions which are used to generate two different report on one gridview. In otherwords, in my design, I have a calendar event which is used to generate a report on the gridview and I have a dropdownlist which is used to generate a different report on the same gridview, so depending on the control that is clicked on depends on the report being generated. Now I would like a situation where my gridview rowdatabound is only applied to the dropdownlist report not the calendar event report. How can i go about doing so.

I'm attempting to change the format of the 2nd column in a gridview during the rowdatabound event. I pulled sample code from various sources and wrote the following, but it's not working. I tried to do a trace, but the rowdatabound event didn't appear in the trace. Here's some code for the gridview:
[Code]....
Here's what I have in the code behind:
[Code]....
I expected the values in the 2nd template column to get written in italics, but nothing happens. I do have a gridview skin that's getting applied.
i have a gird and i want to change particular row color when i found such particular row on row data bound ..
for example when i found a text from "lblRowId" than how can i change current row color or css[Code]..
I have a gridview and a template column:
<asp:TemplateField HeaderText="Active">
<EditItemTemplate>
<asp:CheckBox ID="chkbxActive" runat="server" Checked ='<%# Bind("Active") %>' />
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="lblActive" runat="server" Text='<%# Bind("Active") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
The item "Active" is a bit from the database And for the RowDataBound:
Const HeavyCheckMark As Char = ChrW(&H2714)
For Each row As GridViewRow In gvProductCodes.Rows
If gvProductCodes.EditIndex = -1 Then
' Selects the text from the Label which is inside the GridView control
Dim lblActive As String = CType(row.FindControl("lblActive"), Label).Text
lblActive = lblActive.Replace("True", HeavyCheckMark)
lblActive = lblActive.Replace("False", "")
'Replaces the text in each Label control
CType(row.FindControl("lblActive"), Label).Text = lblActive
Else
Dim chkbx As CheckBox = CType(row.FindControl("chkbxActive"), CheckBox)
End If
The check mark works fine when not in edit mode. But when in edit mode, the row that is being edited works as expected. But the other rows now show True or False. I want them to have the const HeavyCheckMark in it instead.

img = new System.Web.UI.WebControls.Image();
img.ImageUrl =
"http://localhost:47120/green_img.png";
img.Width =
new

When a Gridview row is in edit, I need to default an empty textbox to today's date. I am close, but the defaulted date is is not saved to the database. I can key in the date and the date is displayed and saved to the database. Even more interesting:
1. The date is defaulted to - 5/17/2010
2. If I erase the month and key the "5" back in the data is not saved.
3. If I erase the month and then change the month to "6", the data is saved to the database. If any value is changed in the date the save works.

I ran into this problem I'm sure someone else has similar encounter with, but just couldn't find a solution for it!
I want to disable few entries in the dropdownlist that's in the template field, depending on the value in BoundField when the gridview is being populated.
Below is my attempt:
[Code]....
JobStatus is the dropdownlist in the template field, and Status is the boundfield. In run time, the bolded line causes below exception: Object reference not set to an instance of an object. which I think is wingeing about null variable. Perhaps the templatefields are created after RowDataBound event?
I have a databound gridview in which i have added a template field to display a calcultion. I have created a rowdatabound event in which I want to perform a calculation, but don't know how. The calculation is as follows:
First, it should take the sum of all the payments made by a given customer. It then should divide this value by a daily membership rate, returning a days paid variable. Finally, it should add that variable to the customer since field and calculate the date that the customer is paid through.
