Hi!
How can I open a gridview in edit mode?
Normally if you open a website the gridview isn’t in edit mode. You can edit a row in gridview by clicking on edit button (edit link).
What I want is to open a website (with a grid) and all of the rows are in edit mode. You can edit a column and click on refresh or save.
Thanks in advance!
Best regards

hi Klaus!
I think if you're using TemplateFields in GridView then you can put all the rows by default in edit mode. Actually there is a property called EditIndex. when you set it to a certain row number it changes itself to the edit template. so this is related to a single row you know. Since you want all the rows to be in edit mode. you need to craft this yourself by adding the text boxes etc
I hope it helps you
Thanks

It goes something like this...
Thats only to show the use of Template Fields. You should carry on according to ur req from here
<asp:gridview id="GridView1" autogeneratecolumns="False" runat="server" datasourceid="ObjectDataSource1" horizontalalign="Left" width="205px">
BorderWidth="0px" CellPadding="0" >
<columns>
<asp:templatefield headertext="Refine Search">
<headertemplate>xyz
</headertemplate>
<itemtemplate>
<asp:textbox id="tb1" runat="server" Text='#Eval("DbField")'>
</asp:textbox></itemtemplate>
<footertemplate>
</footertemplate>
</asp:templatefield>
</columns>
</asp:gridview>
Hope that helps
Thanks

Hi,
You can try
//Index of the row to be edited.
GridView1.EditIndex = 0
GridView1.DataBind()

hi,
well u can use it like this
on form's load event ...
if you are using C#.net
if (!IsPostBack)
{
GridView1.EditIndex = 0;//assuming that you want to show first row editable
GridView1.DataSource = "Your DataSource";
GridView1.DataBind();
}

If I use your code, I get an error message, can you tell me why?
Here is my code:
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
GridView1.EditIndex = 0;
GridView1.DataSource = "SqlDataSource1";
GridView1.DataBind();
}
}
}
Here is the error message:
System.InvalidOperationException was unhandled by user code

StackTrace:

Hi,
As you have already defined DataSourceID and DataSource try your code like this
GridView1.EditIndex = 0;
GridView1.DataBind();
The error is generated probably because when you have already assinged DataSource and DataSourceID in designer and try to assign DataSource again in code it gives error.

Hi,
what i believe you will be required to create a method that will check the selected rows of the grid view. when the page is changing call that method and store the selected row in a session. on the next page when user select rows repeat the same process. note that the method will not only be called no the page index change but also where there is some post back on the page.
hope it will help.

My application's session lasts for only 2 or 3 minutes even if I set session timeout to 30 minutes in web.config file.
<system.web>
<sessionState timeout ="30" ></sessionState>
</system.web>
Can anyone tell the reason
|

It's hard to tell what is causing the problem. Are you doing anything that will reset the application, like modifying web.config runtime etc ? If yes it will clear all session variables.
|

Hi,
Check your session timeout in IIS as well. Follow the path
IIS -> Default Website -> YourWebSite -> (right click) Properties -> (from Tab) ASP.Net -> Edit Configuration -> (from Tab) State Management.
Check the session out time here and try to increase it if it is lesser than 30 mins.

hi, i'm posting because i have a problem i can't manage to solve...
i have a page with a row of DropDownLists, and what i want to do is this: when the user selects a value from one of the dropdowns , a new one is created under the selected, with the same values of the previous one, except for the selected one.
i know i have to write a function in c# called from OnSelectedIndexChange, but i can't understand how to create the new ddl from the code..
can anyone one help me or suggest a better way to do that?
i'm working on Visual web Developer using C#
thanks anyway, and sorry for the poor english..
bye

If the second drop down has all the same value, minus the one selected you should be using a multi-select box instead of a select drop down. Then the user can select multiple choices w/o going back and forth between the server and w/o the complexity you're talking about.
If you're doing this to limit the number of choices the user makes, you could do this in javascript. Then on the server-side, validate the data a second time to make sure the user didn't try and bypass your client-side script.

Yes, the second one should have the same values except for the previously selected one. The problem is that after the first selection made with the DropDownList, the user can chose, for the selected value, properties from another DDL, and then another value for this one. So, when the user opens the page, he see a row of DDL. I need that, after the row he finish fulling it, another raw is created under the existing one, and so on, and only the mix of choises done before couldnt be re-done after...
That's the reason why I can't use a multi-select box..
I hope I explaned it well..
About javascript:i'm not used to it, do you really think I can do what I need better using javascript?
how could i do it?
Thanks anyway for the reply

Sounds like I didn't understand what it is you are trying to do. To clarify, it sounds like you are trying to allow the user to fill out a row of DDL. And then AFTER they have completed that row you want to give them a new row of DDL controls, minus the value(s) from the previous row.
If this is the case, then I recommend that when the user has completed the current row you will allow them to submit those changes to the server. You could use the SelectedIndexChanged of the last DDL of the row, or a command button.
When the user submits the selected values, create a new row in your data source and then rebind your Grid or list (whichever you are using) with the updated data source.
Here's an blog post on using the GridView's footer template to insert new rows: http://geekswithblogs.net/casualjim/articles/51360.aspx[^]. Just put all your DDLs into the footer row and proceed as I recommended above.
If your data source isn't meant to actually update a database or some other persisted store, but is just transient form data for some operation then instead of updating a persisted store you can maintain the data source in a session variable until the user has completed their operation. Then clear out the session variable when you are done.
