Hi,

When I use a autogenerated select button in gridview and click on it, the event GridView_selected index changed gets fired.

But I want to fire this event on row click and not on select button click.

How can I Proceed??

Solution 2

Take out "selected index changed" event and add Row_Command event.
this event will even fire if you click "Select" button..hope this helps you..

loop through the gridview rows from javascript and find out the clicked row(tr). and fire a click event for hidden buton..

Solution 1

Please refer my answer - Data GridView selected index changed firing Problem ASP.NET[^].

Update
It seems that without the Select Button, the event is not going to fire. So, do like below.

Make the AutoGenerateSelectButton = "True".
And write OnSelectedIndexChanged Event.

HTML

AutoGenerateSelectButton="True"
OnSelectedIndexChanged="GridView1_SelectedIndexChanged"

Add the below Code in RowDataBound Event.

C#

if (e.Row.RowType == DataControlRowType.Header)
{
    e.Row.Cells[0].Style.Add(HtmlTextWriterStyle.Display, "none");
}

if (e.Row.RowType == DataControlRowType.DataRow)
{
    e.Row.Cells[0].Style.Add(HtmlTextWriterStyle.Display, "none");

    e.Row.Attributes["onclick"] = ClientScript.GetPostBackClientHyperlink(this.GridView1, "Select$" + e.Row.RowIndex);
}

Now it should work perfectly and Select button will not show.

I saw your answer.
i have updated onrowdatabound="GridView1_RowDataBound" event accordingly but this works properly only when i set autogenerateselectbutton as true and not otherwise.

I dont want the select button to be displayed in the grid.

Hi Tadit,
one more improvisation.
I have a hyperlink column in the same grid as discussed earlier.
On the click of hyperlink,the row click event is fired which we did earlier.
I want the page to be redirected on hyperlink click without the rowclick attribute getting fired.

I tried to remove the attribute on the cell in which hyperlink is there. but its not working.

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 17-Jul-13 5:48am

Are you sure that without the button it's not working?
I mean the code inside the RowDataBound event actually adds a onclick event for the row.
But I have not tested that code. Please let me know... If it is not working, then I will try to check and resolve this at my end.

Thanks...

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 5-Aug-13 6:21am

As we have a click event on the row, so I guess it will be fired, if you click anywhere on the row. If you see the html generated, the onclick attribute is added to the row, not to the individual cell, so removing the attribute from the cell will not work.

So, you can do one thing... On that SelectedIndexChanged, check something as a part of your redirection logic and redirect from that event itself. Or is there any problem?

aks.shan 17-Jul-13 6:06am

yes, Its not working without the button.
Please do let me know if u find a solution for this.
Thanks.

aks.shan 5-Aug-13 6:54am

If I assign the navigate url on selectedindexchanged event...the hyperlink is getting attached on when i click on the row and after that it is working fine.
But i want the hyperlink when grid is created.

Note:I am using template field in the grid as hyperlink column.

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 17-Jul-13 6:08am

Ok. Sure. :)

aks.shan 5-Aug-13 6:59am

or else can we apply the attribute on individual cell?

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 17-Jul-13 7:13am

Found a solution. Updating my answer.

aks.shan 5-Aug-13 7:20am

Tadit, I got it worked.
Instead of row attribute i applied the attributes on individual cell and with a for loop i tried it to make it work.
Thanks

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 6-Aug-13 3:53am

Sorry Akshay, I have not worked with any of these.

So, I better suggest you to add another question on Code Project and let others (who know) reply you. In the mean time, I am also searching.

Logic would be

-> find the node expand click event.
-> find the open event of accordion.
-> place the step 2 code inside the step 1 event.

Hi Tadit,

I would like to implement same functonality in Infragistics Webdatagrid.
However i am unable to get the SelectedIndexChanged event as well as rowdatabound event.

How can I Proceed?

Thanks.

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 19-Jul-13 3:11am

I have not worked with Infragistics Webdatagrid, but I found the documentation for you.

Refer - Row Selectors.

Here it says... "The WebDataGrid includes a row selector behavior that allows you to configure how row selection behaves. This sample shows how to setup the grid to display row selectors and row numbering. The behavior can be configured to show or hide row numbering."

Here if you see the demo and click on the Row Number on the First Cell, then Row gets selected.

But, I guess as per the introduction, it can also be hided. There is a behavior property of that grid like below (see the code).


<Behaviors>
    <ig:Activation Enabled="true" />
    <ig:Selection RowSelectType="Multiple" Enabled="true" />
    <ig:RowSelectors RowNumbering="true" Enabled="true" />
    <ig:Paging PagerAppearance="Bottom" PageSize="10" Enabled="true" />
</Behaviors>

And I think if you change the RowNumbering for RowSelectors to false, then you can select row without numbers. But you need to try and check.

And yes, do you know after your question, I have added a Tip yesterday on the question you asked.
Please take a look - Fire GridView SelectedIndexChanged Event without Select Button.

Hi Tadit,
i have a data table.
In that I have two columns like "MSG" and "TO".
For a single message ..I have multiple "TO" records.
For eg:
MSG TO
test akshay
test sameer
test sidd
Hi som

Now using for each loop i want all "TO" as comma separated.
for eg:

MSG TO
test akshay,sameer,sidd
Hi som.

How can i get this??

Thanks-Akshay
