View 1 Repliesi have a gridview which consists of databounds and dropdownlist control. When I press the Add Grid Row Button, it will insert a row.

View 6 RepliesI have a couple of tabs and one has a gridview in. One of the columns on the gridview is a Completed field (Yes / No).
On page load is it possible to show on the tab header the amount of rows that have not been marked as compeleted?
Ie so the tab would look like this:
Orders (2)
and the 2 will show that there are 2 rows on the gridview where completed = no
I have searched all over the internet and there are just too many solutions that basically is not working for me right now unfortunately. i just want to display my gridview header and I dont want to add a blank row in any form.

I have a gridview ...asp 2.0 and VS 2005.The Gridview has template fields and I am using a Header Templete and an Item Template field.Within the Item template fields I am using a asp: table and within the table I am using different asp controls to bind data to the gridview
Here is the issue ...I want that each datafield should align with each other eactly i.e. symmetricaly each column wise.The problem as of now is that as each row of data is displayed in a new table and as a result each column aligns differently.How can I align the columns with each other?
<ItemTemplate>
<asp:Table>
<asp:label> ...<Eval(datafield) </asp:label>[code]....
There is a Dropdown(named "Station") in my code.
<asp:DropDownList ID="DStation" runat="server" Width="100%"></asp:DropDownList>
Im fetching the data saved in DB inside dropdown SelectedValue on page load as below:
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
[Code].....
But its always showing "ABC" (i.e, 1st Id's station) in selectedValue of dropdown, for every "id" dont know why.
I'm currently facing an annoying problem that i can't seem to figure out. I have a gridview in my page, and i wanted to add a second header row to it. Well, i did that without any problems using the code below.
No problems so far. I then intended to add some filter to my gridview and so added a dropdown list in this second header i had created.
I simply added the control i previously had to my cell of the header.
[Code]....
The problem is that now, the SelectedValueChanged event is not firing when i change the value on my dropdown list. If i place her out of the gridview, the event fires normally, when placed inside the gridview the event apparently stops firing.
I have tried this with and without AutoPostback ON, though the final goal would be to have that option on OFF. (The postback would be caused by some other button on the same second header row, allowing the user to combine multiple filters simultaneosly)
I am using Asp.net with C#.
I have one gridivew, which is showing 20 records. And also, in item template of Gridview, I used one dropdownlist. It means there are 20 dropdownlist with all the 20 rows. That dropdownlist is already binded, means showing the records/items - 8 items. No issue with this.
Now, what I want is, when ever, I select any item from the drodownlist against each row in that gridview and click on the button "Save", it will save the id of all row with all the values of dropdownlist.
I just wrote something small up with a GridView databound to the products table of the northwind database to play around with the control. I added a template field and put a checkbox in it, ProductID, ProductName, and UnitCost. I can successfully loop through the GridView and find the rows that have the checkbox checked, and can get ProductName for each row, but keep erroring out on ProductID and UnitCost. It's probably something small, but I just cannot figure it out.Here is what I have so far:

Can I not use row.Cells[i]? The only thing Intellisense gives me that makes any sense is 'rows.Cells[i].Text'... not sure what else to do.

View 1 RepliesI have a gridview and the gridview contains some boundfield, templatefield, checkbox and an update command button.
When I click the update button, I want to update only 2 columns. So I made rest of columns readonly=true.
BUT, there is a template field and I am changing the value of the template field from code behind. like below
[Code]....
I do not want to update the above column. so when I click update button, the rows having value more than 0 is working fine.
BUT The rows displaying "Expired" (value less than 0) showing error. It says "Object reference not set to an instance of an object."
When you click Questions, Tags, Users etc. at the top of stackoverflow, the one you're looking at becomes highlighted orange. This is (usually) done by changing the css of one of them to be 'selected'.
If you have a single template that all your pages are built with, and that template includes these buttons across the top, how do you highlight one of them depending on which page you are viewing?The problem is that you'd have one template, not one for each page.(If it matters, I am using ASP.NET MVC 2 and setting up a Master page)
I have a Grid on my page.When the page is loaded for the first time ther is a list of records displayed in the grid.When I edit the record by edit link button,the ddl saves the change value .
The same thing if I do when searching for a particular record and then editing and changeing the dropdownlist value,the page postbacks and the new value gets replaced with the old value that was present earlier.
I have the following gridview...
[Code]....
And inside that gridview you can see I have a dropdownlist called dpdTrueFalse. That dropdown has two values which I am loading from code behind like this...
[Code]....
I have a submit button outside that gridview that checks each row and the selected value in the dropdown. But for some reason, even if you select another item in the dropdown, it always selects the first item in the dropdown when I click the submit button. I reckon its because of the postback.
I want to display a GridView using the the selected DataValueField from the DropdownList.
I've set the Selectparameters for the GridView DataSource.
Here is my question: on clicking "BtnSelect" - How do I assign this parameter (@Id) to selected value (DataValueField) from the DropDownList and re-display the grid view accordingly?

I am using the SQLDataSource control and binding it to a gridview. When there are no records returned the gridview header is not showing. I want it to show no matter what is returned. I am not calling a stored procedure - I am writing my own select statement in the SelectCommand. How to show the header with no results? I searched but did not find an answer when using the SQLDataSource.
