Forms Data Controls :: Event Not Firing When Using Calendar Control Within GridView
Mar 15, 2010
In a .Net 2.0 project, I have a Calendar control within a GridView that has a method set for its OnSelectionChanged event. However, the event never fires and I don't understand why. Here's what's in my aspx page:
I am facing one strange problem,I have a gridview in which the last two columns have checkboxes and on those checkboxes click event I am doing some database operations.I also have one checkbox that is outside the gridview which actually shows or hides some of the gidview columns.This was all working well but now I have shifted that grid to a user control because I have to use it in two pages.The problem now is,When the page first loads and I click the check box or any control in the page that is outside the grid then it works perfectly.But once I click any of the check box within grid view column then its behavior chages, now even if I click the checkbox that is outside the grid then also the checkbox_CheckedChanged event of the checkbox that is whithin gridview is fired.That checkbox event then behaves something like a page_load event that is called for every page load and for every event with in the page after it is called once.
I have a gridview,sqldatasource and a link button for delete in the sample code below
When Delete is click the confirmation pops up. When I confirm yes, the rowdeleting event doesn't seem to be firing. I addeed a label to see if the event is firing. To avoid runtime errors I added a dummy but actual sql delete command. Once If I get it to work, I want call a stored procedure to delete the row.
My question is
1. Why is the gridview row deleting event not fired.
I have a very simple page that consisist of an UpdatePanel that contains a gridview. The gridview includes a delete button for each row, which should fire the Delete event. But the event never fires. If I set a breakpoint inside the event handler, it never gets hit and the row does not get deleted. When I say OK on the confirm dialog it just goes back to the page. I tried taking out the confirm button extender
I have an inner gridview called MyInnerGridView and I have operations I need to do in the Row_Updating event but this event is only firing for the last row of the outer gridview. I have pared down the sub to the following and the exception is only thrown when I try to edit an inner gridview record of the last record of the outer gridview.
[Code]....
why this is happening when I edit an inner gridview record of the last row of the outer gridview?
[Code].... all of a sudden my GridView has stopped firing the row update event. Friday I was working on it and was working flawlessly. Now I haven't made any changes to the code and all of a suddent has stopped working (yes rediculously bizarre and have been banging my head all day thinking what the something is wrong with it, excuse my french).
Everyone of those events fire except the update. I click the update button and nothing happens.
I am trying to create a custom GridView with a header toolbar at the top that will contain icons to export the grid view to different formats like excel, word, etc.. The problem is, I cannot get the method to fire that is assigned to handle the click event for the corresponding Image Button. The page posts back, but the code I have in the method to handle the click event does not fire. I have followed examples in other posts and from what I can tell I have followed what others have done. Can somebody take a look at see if they can find something that I am doing wrong.
I have a set of validation controls on my asp.net page, to validate values in textfields. I also have a calendar control on the same page. When I click on the calendar image, the validation control message box pops up. How can I avoid that from appearing when the calendar icon is clicked?
I have a Master/Slave GrisViews or some say Parent/Child GridViews.
i want to set my button visible=false in the child gridview if data is not exist.
i try this:
Protected Sub gv_child_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) If e.Row.RowType = DataControlRowType.DataRow Then e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#FFC080';") e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='';") Dim lblitemid As Label = CType(e.Row.Cells(1).Controls(1), Label) Dim lblphoto As Label = CType(e.Row.Cells(11).Controls(1), Label)
[Code]......
but it does not working. the button is still there.
I have a gridview that has 20 columns in it. 3 of them are date fields. I am using templatefields but not edittemplates, only itemtemplates because the users want to update multiple rows and then update the data all at once. I have a panel with an update panel and a calendar on it and in the grid I have a popup extendar added to the textbox in the cell to make the calendar show but I can't get the value from the popup calendar back to the cell. Does anybody have an example or is there a better way to do this?
On grid RowDataBound based on some condition i've added imagebutton dynamically. parallelly i want to add event for this button click. here is my code snippet.
protected void GV3_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { TableCell cell = new TableCell(); ImageButton bttn = new ImageButton();
[Code]...
That message popup box comes, but i'm unable to catch that click event. while click on a row i want to delete that row, so want to create event dynamically. for that i've used this following dynamic click event
bttn.Click += new ImageClickEventHandler(b_Click); private void b_Click(object sender, EventArgs e) { //delete record }
I have an UpdatePanel with a GridView. This GridView has a template column that is a DropDownList. The problem is that the SelectedIndexChanged event does not fire for the DropDownList. Here is the code:
I am using C# ASP .NET 2.0. On my web form I have a GridView and a Calendar control and I want to do the following:
With the Calendar control, I only want to show the current month, and links for the previous month and next month. Not the actual days of the month.
I want the days in the Calendar control to populate my left-most column of my GridView. For example, if March was the current month then I should see 31 rows in my GridView starting with 03/01/2010 in the first row and 03/31/2010 in the last row.
When you click the previous month or next month link I need the GridView to change for the selected month.
I have a gridview called gvResults. In the gvResults_RowEditing event I add a row below the one selected. In that new row, which spans all columns, I insert a user-control. There are two buttons and some textboxes in the user control.
My problem is that when I click one of the user-control buttons it never gets to the button event handler, I think because the user control is not recreated on the page postback. How can I have the user-control events fire before the parent page events fire?
I tried using an update panel, but I still get the parent posting back before the user-control events.
I have simple SQL DB with invoice informations (i.e. invoice date, client info etc.). I'd like to use 'selecteddates' from the Calendar control to show the invoice information in a gridview with the invoice dates which are in the 'selecteddates' group.
* Calendar control * Gridview control for games (uses SqlDataSource1, set to a stored procedure that requires 1 parameter: date) * Gridview control for videos (uses SqlDataSource2, set to a stored procedure that required 1 parameter: gameID)
This is my intended functionality:
* only control visible at start-up is the calendar control * user selects a date from the calendar control * the Game gridview becomes visible, showing games on the date the user selected in the Calendar control * the user selects a row in the Games gridview * the Video gridview becomes visible, showing available videos for the game
If I remove the Calendar control, the functionality between the Games gridview and the Videos gridview works as intended:
However, when I add the Calendar control, and change the datasource of the Games gridview to be dependent on the date selected in the Calendar control, the Video gridview no longer works
I was having issues with a gridview and CSS so I posted my question here and received a wonderful answer which lead me to implementing CSS Friendly Adapters for all of my gridviews.I have a table nested in the EditItemTemplate that holds the textbox and the button for a calendar control where I want them, it inherits the CSS applied from the CSS Friendly Adapters. I don't want it to change the CSS so I have changed the CSS inline, with no success. More importantly...
I also have a Ajax calendarExtender control to change the date for that field. When the popup is displayed the table in which the calendar is shown in also inherits the CSS Friendly Adapters code. I have tried fixing this by creating a external css sheet for the calendarExtender's cssClass property and a blending of CSS occurs where the items not specified by the Friendly Adapter Code are set correctly by the calendar.css file that I created.Is there anything that I can do to force the tables inside of the gridview to ignore the inherited Friendly Adapter Code?
