I have an item template field retrieving a date field from an Oracle 11g database that can be null. The date is converted to a string before binding to the gridview. When the column is sorted is is being sorted as a string. I have read in several places if you add a formatting string to the eval statement in the item template that the sort operation will then sort the string as a date. However, I cannot get it to work. I also tried a bound column, but the column is still being sorted as a string.Code from the aspx page:
<asp:TemplateField HeaderText="Comp Date">
<HeaderTemplate>
<asp:LinkButton ID="sortDatea" runat="server" CommandName="Sort"
[code]...
I need to set the HeaderText of GridView BoundField in codebehind file based on a flag at runtime.
I tried setting the column name as
e.Row.Cells[0].Text = "XXXX";
It is worked out but not able to sort that column.
here my requirement is to set the HeaderText programmatically in codebehind and able to sort the column.
[Code]....
when image display, there is a space where the template headertext resides.
how do i remove the header space (vertical line )completely to leave just the imagebutton.
I am using VS2008.I am binding dynamic datatable to gridview. I have few dropdowns and textboxes in gridview.
I have dropdownlist(ddlTrCodeNw_)in gridview foooter template. Based on the selection of Trcode value few controls will be enabled,disabled,visible,hide. in gridview.
<asp:GridView ID="gvAPPost" runat="server" Width="100%" ShowFooter="true"
AllowPaging="true" AutoGenerateColumns="false"
onrowcommand="gvAPPost_RowCommand"
onrowdatabound="gvAPPost_RowDataBound"
>
<Columns>
<asp:TemplateField HeaderText="Discount %" Visible="false">
<FooterTemplate>
<asp:TextBox ID="txtDiscountPerNw" runat="server" Width="40px" Enabled="false" Visible="false" ></asp:TextBox >
</FooterTemplate>
<ItemTemplate>
<asp:TextBox ID="txtDiscountPer" runat="server" Width="40px" Enabled="false" Visible="false"></asp:TextBox >
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
Intially I set TemplateField HeaderText also Visible="false".
so i have written the condition in ddlTrCodeNw_SelectedIndexChanged.
Now when
if(ddlTrCodeNw.SelectedValue=="24")
{
txtDepstNw.Enabled = true;
txtDepstIncNw.Enabled = true;
txtCrdtNw.Enabled = false;
txtCrdtIncNw.Enabled = false;
lblDiscTrcodeNw.Visible = true; // I want to show this TemplateField HeaderText also when i need.
}
I can I show TemplateField HeaderText also whenever i need.
I have a formview with various templates set up for a database that has 255 columns. I need the insertitemtemplate to pre-fill values based upon a specific selection by the user (just like the edit item template) but when the template is switched to insertitemtemplate every text box is cleared. The idea is that a new entry is usually made by making minor changes to an existing entry. With 255 fields I don't want to require the user to enter every field when only three or four need to change.
View 8 RepliesI have a gridview which the columns are created programmatically.
When a button is click i will clear all columns and add the columns that I want. Im adding a boundfield which is not a problem. When I add a template field, I must add also the item template which is my problem.
How can I add a item template in the template field I created which is binded in my datasource. Also what event handler should I use to do this.
Here's the part of my code:
[Code]....
Someone know how can I bind a label item template from the datasource. The label item template should be firstname + middlename + lastname.
If im not doing it programatically, it will be just concatenating eval(). But how can create item template and bind it programmatically?
can i implement multiple column sorting in an ASP.NET DataGrid.Datagrid contains Template columns.
View 5 RepliesI have a gridview control set up like so:
[Code]....
I am using an IComparer to do the sorting of the gridview and binding it to a list of objects. It used to be that the linkbutton in the first template field was being done like this:
[Code]....
The sorting worked just fine when it was like this, but I would prefer not to use a querystring value. The problem with using the linkbutton is that the sorting appears to work (there are only two rows in my test case and they change places), but when the linkbutton is clicked on it is in the same order before the sort took place. After each sort the gridview's datasource is reset to the newly sorted list of objects and the databind method is called.
i want to write a page contain an datalist and several ObjectDataSource. The datalist will chose ObjectDataSource according to QuerryString passed to that page.
My idea is like:

I searched and read [URL]
I have a gridview to which I'm adding template fields programmatically. Each of the template fields have a textbox. I would like to make this text box have 2-way binding to a database column. see below code.
[Code]....
I'm calling the above class as follows
[Code]....
How can I make the text box such that when I edit the text, this change is reflected in the database as well?
I have an application that I would like to be able to allow the user to modify multiple characteristics of each record within a datagrid.
Most characteristics require data to be entered in a text box but some a check box would be more appropriate.
My question is does a gridview column need to have all the same item template controls? or could I read from the database the control type and dynamically alter the template control for each row as it loads?
i am implementing a update query module.i am displaying all fields from a table for a term searched. well now i am implementing update option for the record which are displayed, i have like 70 columns in my table, and i want to know how to restrict some selected fields to be only read only while the form can be updated ?Like if user select to update a record then some selected field such as "Timestamp, UID etc some selected fields" remains READ ONLY !
View 1 RepliesI have the following line to display a piece of data and I want to know how I can format the output.
Text='<%# Eval("DOH") %>'
The data list displays the correct data, but I want to format it. The output I want is just a small date format instead of date and time. I have tried every combination of a format function I can think of, but can't seem to make it work. Am I stuck with the raw format provided by the database? I wouldn't think so, but maybe that is the case.
expected output should be 02/15/2011 instead of 02/15/2011 09:45:

View 2 RepliesI have a dropdownlist as a template item in a gridview - it populates fine and with the right values. I have an SelectedIndexChanged on the dropdownlist, and has set it for postback. In the SelectedIndexChanged event, I would like to know where the control that fired this event is, - which row in the gridview is it in? How do I get this info? If the row was selected it would be easy, but the only thing that has happened in that row is that the dropdown has changed value and consequently the SelectedIndexChanged event has been fired - is that enough to know which row the event has been fired from?

I have one gridivew, which is showing 20 records. And also, in item template of Gridview, I used one dropdownlist. It means there are 20 dropdownlist with all the 20 rows. That dropdownlist is already binded, means showing the records/items - 8 items. No issue with this.
Now, what I want is, when ever, I select any item from the drodownlist against each row in that gridview and click on the button "Save", it will save the id of all row with all the values of dropdownlist.
The Detailsview has a template containing a textbox for one of it's fields.When an item is selected in the Gridview, I want to set a property of the textbox. How do I do that? I've tried Findcontrol for the item during Prerender of the detailsview. I've also tried many other things. Below is a portion of my aspx code followed by my VB code.
