View 5 RepliesIt happened to add an extra Gridveiw Header in row_databound event , It did worked fine on !Postback but disappered on Page.Postback . Quick google search guided me to move the event to Row_Created event and every thing is okay .
Can any expert post some pointers , differnces between grid row_created vs row_databount with some sample table data created dynamically behaviour of both the events in !Postback and page.Postback .
I am doing a online web application whereby user is able to enter in new template as well as search for template. The Add template is located outside the grid view and if user clicks on the button, it will load the grid view that is populated with data as there is a row of empty fields at the bottom. However when I click on the Add Template button, the grid view does not appear.
This is my business logic that I used it to search for records as well to click on the Add Template button to add in new records:

View 4 RepliesI am trying to capture the SelectedIndexChanged event for a drop down list I have put inside of a gridview control. It posts back fine, but does not go into my SelectedIndexChanged event handler. Here is my code
[Code]....
it is still not going into my myddl_SelectedIndexChanged() eventhandler.
I am using grid view control with paging Like-:
protected
void grdUpdateColumn_RowCreated(object
sender, GridViewRowEventArgs
e)
{
if (e.Row.RowType ==
DataControlRowType.Pager)
{
DropDownList ddl
= new
DropDownList();
//adds variants of pager size
ddl.Items.Add(
"5"
);
ddl.Items.Add(
"10"
);
ddl.Items.Add(
"20"
);
ddl.Items.Add(
"50");
ddl.AutoPostBack = true;
//selects item due to the GridView current page size
ListItem
li = ddl.Items.FindByText(grdUpdateColumn.PageSize.ToString());
if (li !=
null
)
ddl.SelectedIndex = ddl.Items.IndexOf(li);
ddl.SelectedIndexChanged +=
new
EventHandler(ddl_SelectedIndexChanged);
//adds dropdownlist in the additional cell to the pager table
Table pagerTable = e.Row.FindControl("pagerTable")as
Table;
//e.Row.Cells[0].Controls[0] as Table;
TableCell cell =
new
TableCell

cell.Style[

void ddl_SelectedIndexChanged(object
sender, EventArgs
e)
{
//changes page size
grdUpdateColumn.PageSize = int.Parse(((DropDownList)sender).SelectedValue);
ViewState["Index"]
= 1;
//binds data source
this.GetChangesRecord();
}
Grid view Like -:
<PagerTemplate>
<asp:Table
ID="pagerTable"
runat="server"><asp:TableRow>
</asp:TableRow>
It's working fine but problem is that if i select 10 and record from dropdown and record also has 10 then paging is not showing.
That's mean i select 10 from dropdown and record is 10 then dropdown also disable with numbers, suppose i need to select again 5 then i can't do this.
I have a requirement in my application that, while saving the application, need to get all the value from drop down list and pass it to the view model. But application should not allow the user to select more than one item from drop down list manually, ie, only one value at a time. My view model is like ...
public class ListManagement
{
public IEnumerable<selectListItem> InactiveProduct { get; set; }
public string[] InactiveProductSelected { get; set; }
public IEnumerable<selectListItem> ActiveProduct { get; set; }
}

View 1 RepliesI've got and SqlDataSource bound to a GridView, and I'd like to return the value of one of the fields from the SqlDataSource during GridView.RowCreated (I think). At the same time, one of the fields I'm returning to the GridView has a Null value, which I'm cool with, but Runtime is complaining about it so how can I get around errors relating to Null values in my tables?

I have a grid view and I am unable to get the values that I edited from the grid view using below code. Can Any one look into it and advise what is wrong with my code?
View 11 Repliesi have a drop down list and a text box, inside a listview row (and this is a repeating layout). i populate each dropdownlist with same contents ( these contents/items come from a custom collection object).
i have added a required field validator in the listview's item template, that has its validation group = the validation group of the drop down list, and validates if the textbox is blank or not. this validation takes place on the selected index changed of the drop downlist for that row.
1. on selected index changed, EACH dropdownlist validates only its corressponding textbox perfectly (which is what i want)
but if i enter some text in one of the textboxes after doing 1, the dropdownlist for THAT particular row, assigns the correct value to the text entered. but for other rows (for which i changed their corresponding ddls to test the required field validation and for which the text boxes are still blank), their ddls by itself assign the values to the blank text without validating.
markup of code for listview is [Code]....
code behind for the ddl selected index changed is [Code]....
method GetIndexFromId retrieves index of the custom object inside a collection depending on the Id (which is a property) of the object.
i notice that the ddl selectedindexchanged is being hit as many number of times as many rows i change (i.e as many ddls in different rows i change to check the required field validation)
i need to create a list view that displays items circularly. (that is when the top most item is hiding a new item should appear at the bottom)
