I need to be able to get the value in the "first" row of a Gridview as its getting or right after it is displayed.
I thought this would work but its coming up null.
I'm using the DataBound event to get the value of the control of a selected row...assuming the selected row is the first row which is probably the error of my ways. Any ideas how to get at this value easily?

View 3 RepliesI have a gridview with dropdown boxes. As soon as the complete gridview is databound, I want to loop through ALL the rows and set the values of the dropdown boxe in a row based on the value of another column in the same row. The gridview is databound, all data shows up. The condition "If ddl.Items(j).Value = searchstring Then" evaluates as true, but somehow the selected item in the dropdownbox is NOT changed and remains "<ignore>"

So I am uding a GridView bound to a SQL data source.
I have a template feild bound to a SQL BIT
<EditItemTemplate <asp:CheckBox ID="chkSelected" runat="server" Checked='<%# Bind("Selected") %>
The original Item Template was Enabled ="false" I changed this so that you did not have to set the row to a state of edit in order to just select a row. I enabled it so that you could "select" any row with out putting it in a state of edit. the only value changing is if its selected or not. What i am trying to do is use the Data Source Update method to update the bit in the database based on the check box. Currently Update() returns 0. I believe this is because the row/feild is not marked as changed so the Data Source does not see it as something that needs to be updated.
What I am hoping for out of this is post is a way that the rows whom check value has changed to be marked as changed/edited so that the data source will update the database with the values of the check boxes. If all rows are updated this is acceptable as well. I know this is a super simple solution but i have been out of the .NET for a little bit.
I am facing certain problems with the data formatting in GridView when the data is bound dynamically to it.
I have a DateTime column and want to only show Date from it and not the time.
Another Decimal type column which accepts decimal upto 4 places, I want to show decimal upto the places defined in the particular value (don't know how to put it in the correct way, but here is an example of what I want).
i.e.
1.0000 should be displayed as 1 after the databound in the gridview.
Similarly,
2.3400 --> 2.34
1.0050 --> 1.005
1.1000 --> 1.1
im building a simple message messenger web application, i currently have a column in my database dedicated to the status of a message. Its bound to the third column in a datagrid.
After converting the column to a TemplateField and using a Label to fetch the data how do i change the text from the database to a small message, e.g. if the data in the database (as an interger) is 0. how do i change the interger to a string to display "UnRead". Do i need to do this during the databinding call or after the grid has been databound?
I know it would be easier to use a boolean and checkbox control but the interger column represents more values than true or false.
I have a stored procedure (For Eg: sp_GetAvlData) that accepts a number of parameters, 3 of which are TimeFrom, TimeTo (as varchar) and TimeInterval (as int), formulates a Dynamic query and executes itself. So for instance, if I call the proc as follows:
[code]....
dtAvl is the datatable containing the results of my stored procedure.
The next step for me is to make each of the cells (except the cells in the first column) as a Hyperlink so that when clicked upon a cell, it populates 2 textboxes with the selected Timeslot and Name or ID (ID field is not displayed in Gridview). The textboxes are located on the same page but outside of the Gridview control.
The Challenge that I'm facing out here are:
1) As you can see, the field names being generated are not fixed and I have no control over them.
2) Because the field names are not fixed I'm not sure I can implement this using the Templatefields or BoundFields of Gridview.
Is there any way to achieve the Hyperlinking of these cells within the Gridview?
I have a data gridview with two columns (Databound- HTML tags), very similar to the one of twitter,the second column populated as follows:
USERNAME: COMMENTDate
i need to add "Report this Comment" button next to the date, once clicked the user will be forward it to another form holding all of the above information related to this special row.
I have a datagridview that has a column which displays a ref value from another unbound table, but during an edit of a gridview entry i want a dropdownlistbox to list all the available ref values from the other unbound table source, then to insert the selected value into the bound table
View 1 Repliesthis is my hyperlink code that is in gridview

I want do some thing like that for my button control that is not in gridview it is out of grid view...HOw I can do it?
This is my for loop code, it is working fine , just the problem is, if there are 10 rows , it runs for 9 rows and not for 10th time? What correction is needed?

I am using TempleteFields for all columns in my GridView. In that columns I am using only some fields for customization but not all.
Is there any performance issue with Databound Fields vs Templete Fields in a GridView...?
Do I need to replace the remaining columns with Databound Columns instead of TempletField columns...?

View 2 RepliesIt happened to add an extra Gridveiw Header in row_databound event , It did worked fine on !Postback but disappered on Page.Postback . Quick google search guided me to move the event to Row_Created event and every thing is okay .

I want to render something like this (with ASP.Net Controls in the codebehind):
<ul>
<li class="first"><h1>This is a caption</h1></li>
<li><a href="#" title="" target="_self">Foo</a></li>
<li><a href="#" title="" target="_self">Foo1</a></li>
<li><a href="#" title="" target="_self">Foo2</a></li>
<li><a href="#" title="" target="_self">Foo3</a></li>
<li><a href="#" title="" target="_self">Foo4</a></li>
</ul>
<ul>
<li class="first"><h1>This is a another caption</h1></li>
<li><a href="#" title="" target="_self">Foo5</a></li>
<li><a href="#" title="" target="_self">Foo6</a></li>
<li><a href="#" title="" target="_self">Foo7</a></li>
<li><a href="#" title="" target="_self">Foo8</a></li>
<li><a href="#" title="" target="_self">Foo9</a></li>
<li><a href="#" title="" target="_self">Foo10</a></li>
<li><a href="#" title="" target="_self">Foo11</a></li>
</ul>
The amount of li elements that will be rendered into each ul is determined at runtime. Each link in a li belongs to into a specific ul (the one containing a specific caption. Imagine this as a kind of a treeview with nodes and subnodes) During the bind Event I need access to an ASP:HyperLink that will be rendered into the a-element. Which databound ASP.Net control should I pick for this? Looks like a repeater in a repeater, which should make the databinding process ugly. I'm thinking about creating this HTML-Output with StringWriters myself.
If the gridview binds to empty dataset, I need to still show a gridview so that users can ADD more using the textfields in the bottom of the footer template. Since the gridview is empty it won't bind not allowing rendering of the <footer template> I guess I should create a empty dataset if the gridview is empty. How do I check for this and can this be done in GridviewRowEventArgs
