What is happening here: there is already exist one TextBox in TableCell by default and I want to add another one TextBox and Label. After the bounding I can see 2 textboxes, I can input data into the both, but when I click Update button, then raises OnRowUpdating event where I can't get my TextBox!
protected void RowUpdating(object sender, GridViewUpdateEventArgs e)
{
grdView.EditIndex = -1;
int counter = 0;
for (counter = 0; counter < grdView.Rows[e.RowIndex].Cells.Count; counter++)
{
foreach (Control ctl in grdView.Rows[e.RowIndex].Cells[counter].Controls)
{
And here I will be getting only default one TextBox (with its value). But my TextBox is disappeared! :(
P.S. I can't use predifined columns, like asp:TemplateField in aspx file, because my table has different amount of rows every time. It is dynamic
All of my columns are bound in the Gridview. On OnRowDataBound event, I am adding some custom styles like underlines and colors to the text of the columns. Sorting of data is working fine but I am losing my custom styles when I sort. I am using the generic sorting code for the GridView.
How I can keep my custom styles on sorting that I added during OnRowDataBound event.
I know that if I re-add the control during Page_Load, the posted values will be repopulated when the page is rendered; however, this is not the case when re-adding the control during the Click event and I need to add the control during an event handler.
I've an UpdatePanel where according to operations inside of this UP is filled. I've add some buttons but the buttons to not fire clicks. I've used the code
Button b = new Button(); b.Click += new EventHandler(ClickMe); ... void ClickMe(object sender, EventArgs e);
I add linkbutton controls dynamically to a panel, this works fine, but I also add eventhandlers to them like this.. AddHandler mLink.Click, AddressOf mLink_OnClick But when I click the linkbutton links, the event never happend. I have one updatepanel wrapped around some panels. What could be wrong?
I have a gridview that on it's RowDataBound event I dynamically add Image Controls to some columns.
The problem is that I lose these images on the next PostBack.
OBS: The GridView's EnableViewState propertie is already set to true
I know about the page lifecycle, but how can I persist these images if I have to add them on the RowDataBound event?
In addittion, if I add a static TemplateColumn with an Image Control and I set it's ImageUrl propertie inside the RowDataBound event it will obviously persist between postbacks. The problem is that I don't know how many columns with images I'll have, it's defined on the datasource.
I'm using a standard GridView control inside of a web form. The web form uses a master page. The application is running within sharepoint (wss 3.0) environment. When i attach both the OnRowCommand and OnRowDatabound events to the gridview as shown in the markup below, only the OnRowDataBound event fires. The OnRowCommand never gets hit. When i press a button on a row, it posts back but never hits the onRowCommand event and simply falls through and repaints the page . However if i remove the OnRowDataBound event, the OnRowCommand event starts to fires correctly. I've tried a number of things...1. Hooking up the events in code instead of markup. (inside of PageLoad or PageInit)2. Changing the order in which the events are attached.
I use an objectdatasource programmatically to use a parameterless method when SearchWord variable is empty and a Search method with one parameter when SearchWord is not empty, the event I use is objectdatasource selecting so that I can adjust parameters conveniently, I have a problem here: I can add a new parameter and set its value but I can't remove a previously added parameter from objectdatasource selectparameters and an error raises because of this, this is the selecting method:
[Code]....
Both adding and removing the search parameter takes place in this method while adding works removing the added one Not works.
Actually the controls are in a user control on an aspx page that also uses a master page (if that matters)
I defined a table in the skin file with TableHeaderRow, HeaderTableCell. I added some formatting to these entries. The table defined in the control is not being skinned by this definition. If I add a "CssClass" on the TableHeaderCell in the control, the formatting works fine. If I add the CssClass to the skin it doesn't work.
When the user selects an "account" we dynamically create a linkbutton with the selected dates. However, the linkbutton onclick handler doesn't fire when the button is clicked.
Dim linkBtn As New LinkButton linkBtn.Text = "blah" AddHandler linkBtn.Click, AddressOf linkButtonHandler linkBtn.ID = panelDatesRencontre.Controls.OfType(Of LinkButton).Count panelDatesRencontre.Controls.Add(linkBtn) ScriptManager1.RegisterAsyncPostBackControl(linkBtn) Dim Trigger1 As New AsyncPostBackTrigger Trigger1.ControlID = linkBtn.ID Trigger1.EventName = "Click" UpdatePanel2.Triggers.Add(Trigger1)
Answer: i make that in page_load, it seems to work
I have a Web Site project, and within it I have a user Web Control defined in an ascx file.The control is added to the Site.Master, and it shows up correctly on the page and everything is fine.I need to override some of the control's fields on one of the pages that derive from Site.Master.
// In OnLoad: MyControlName control = (MyControlName) Page.Master.GetBaseMasterPage().FindControl("controlID"));
The issue is that MyControlName doesn't register as a valid Type on the child page. If I add a second instance of the control to the child page directly, the above works as needed, but if the control isn't placed directly on the page, and instead is only defined in the master page, the type is undefined. The control is not in a namespace, and is defined within the project, so I don't know why it is having such an issue location the appropriate type.If I put a breakpoint in the OnLoad, the type listed for the control is ASP.my_control_name_ascx, but using that does not work either. Why can't the child class reference the correct type? Can I fix this?
I've got a problem with my onrowdatabound function. The situation is like this:
protected void gvSQL_RowDataBound(Object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { switch (Session["Filter"].ToString()) { case "NonZero": if (e.Row.Cells[9].Text == "0") { e.Row.Visible = false; } break; } } }
At the end I need to kill the Session, so my plan is to detect if it reaches the last row. Then I can kill it. Does anyone know how to do this? Or is there someone that knows a better to fix this?
I have a nested gridview dynamically added. It seems I resolved all issues with the loading this control on a parent page along with other controls and I can trigger the edit of the first level - the master part of the gridview. However, I cannot trigger the edit on a child gridview.
OnRowEditing="grdChildGridEdit_RowEditing"
The master and the child gridviews have objectdatasources in a markup but I have to do the additional data binding after the loading the control on the parent page (see the code below). I'm doing that additional data binding only for the master gridview that is working fine and shows the data for the master and the child gridviews. When I click the Edit button on the master gridview it shows text boxes for the editing but when I click the Edit button on the child gridview it's doing nothing and moreover the editing mode for the master gridview is going back to the initial stage (labels).
I was trying to trigger it throughuse the registering the event:
