Mar 25, 2010
i have a gridview which consists of databounds and dropdownlist control. When I press the Add Grid Row Button, it will insert a row. Now my question is, if the user selected an item in dropdownList in the firstrow and the user click the AddGridRowBtn Again which will generate the 2nd row, how would i maintain the selectedItem in the dropdownlist after postback?

I am using Asp.net with C#.
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.

I have a webform developed in VB.NET and I am facing a strange problem. In the webform I have a GridView control which has two bound fields (Item # and Item name) coming from a master table and infront of these two fields I have placed a TEXTBOX control as TEMPLATE FIELD to take any value of particular item. But after filling all the textboxes when i clicked on submit button it loops thru the items and there i need to read the textbox value of that particular item in a variable but unfortunately the value is blank even the data is there. Here is the ASPX code.

I have a gridview ...asp 2.0 and VS 2005.The Gridview has template fields and I am using a Header Templete and an Item Template field.Within the Item template fields I am using a asp: table and within the table I am using different asp controls to bind data to the gridview
Here is the issue ...I want that each datafield should align with each other eactly i.e. symmetricaly each column wise.The problem as of now is that as each row of data is displayed in a new table and as a result each column aligns differently.How can I align the columns with each other?
<ItemTemplate>
<asp:Table>
<asp:label> ...<Eval(datafield) </asp:label>[code]....

I have seen several Web Sites that use GridViews that have lookup fields with different Value and Text Fields (as in drop down lists) but I can't seem to figure it out how to display the Text Field in the Item Template when the Text Field is not in the datasource. .
Here's what I have. I have a Gridview whose datasource is a Linq to SQL Invoice table, e.g.
InvoiceID
CustomerID
InvoiceNumber
THe Customer table is related to the Invoice Table thru the CustomerID. The relationship is defined in SQL Server and is displayed in the DBML.
I have created a template field for the CustomerID field in the Gridview. I would like to display the CustomerName when the Item Template is displayed and a DropDownList in the Edit Template. The DropDownList works great, but I cannot seem to figure out how to display the CustomerName in then Item Template.
I seem to remember seeing in some video that you can simply drag the CustomerName into the CustomerID Item Template Field. But I can't seem to find the customerName field. The DataSource includes the Customer Table because of the relationship, but no fields are displayed.
I suspect this is real simple, but I cannot seem to find an article or video that explains how to do this.

I 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?

I just wrote something small up with a GridView databound to the products table of the northwind database to play around with the control. I added a template field and put a checkbox in it, ProductID, ProductName, and UnitCost. I can successfully loop through the GridView and find the rows that have the checkbox checked, and can get ProductName for each row, but keep erroring out on ProductID and UnitCost. It's probably something small, but I just cannot figure it out.Here is what I have so far:
[Code]....
My code behind, where I handle a button click event to get all values in rows w/ selected checkboxes:
[Code]....
Can I not use row.Cells[i]? The only thing Intellisense gives me that makes any sense is 'rows.Cells[i].Text'... not sure what else to do.

I have Gridview that is populated from a data table, there are two additional template columns which are not bound (one checkbox and one textbox). I intend for the users to fill data in the unbound textbox and check the checkbox as needed. (there really is a good reason why the data is constructed in this way)
here is the problem, when the user enteres data into the textbox and hits enter, the gridview appears to postback, which wipes out the checkbox and the data in the textbox.
I tried setting the enable view state of the grid to false, that was supposed to stop postback but no luck. I have the enable view state of the textbox and checkbox set to true and autopostback set to false. but still no luck
so I need to either stop the postback or intercept the enter key in the text box and cancel the action, but that is a bit beyond me at this point

Setting up the editItem template of a gridview. I have a template field with a dropdown list for editing. When the gridview goes into edit mode the dropdown list is displayed with all the right options but the current value of the field (pre-editing) is not the selected value of the dropdown list? How do I make that happen? I have a couple fields where the editItem template will use a dropdown list and I'm sure a user will not realize those values have changed and they will just edit what they intended to edit and save the changes, inadvertently also making changes to other fields.

I've been struggling with trying to figure out how to do this for about 2 weeks now. I have a DetailsView with several template fields in it. The first field (Unit_Code) is a dropdownlist item where the user would select a Unit based off the Unit_Code's Unit Name. Further down I have a field named (System), system needs to get it's value from the selectedvalue or selectedindex that the user selected in the (Unit_Code) dropdownlist. I have another dropdownlist item (Component) that will need to get the selected value from System to sort on, so once I have the first Unit_Code to System figured out I should be able to figure out the System to Component part seeing as it will basically be doing the same thing.
My aspx page code is below:

I have 2 dropdownlist controls (ddl1 and ddl2). When I pick an item from ddl1, it will update ddl2. The problem is when I pick an item in ddl2, it always selects the first item in the list. Is it that the ddl2 autopostback causes the first ddl1 to reload and results the ddl2 to be refreshed also? Or I didn't set something correctly?

I have a HyperLink control in a ListView, and I need to pass a couple of querystring parameters.
[Code]....
The first parameter is based on the current DataItem value in the LV.
Suppose I want to set a second parameter with a value from Selected.Item.Text in a DropDownList on the same page, how would the HyperLink look?

I have a DataGrid that has a dropdown list in an ItemTemplate. Basically, users select a value from the dropdown for each row of the datagrid. When the page is posted back, the selected index of the dropdown list is always reset to 0, and the items are re-bound.
Does anyone know why this might happend? The dropdown items are hardcoded, so there is no external data binding that happens on post back.
