How to solve it? Originally i want to invoke a page method.
I have a problem that if I pass a string that contain + in a query string and try to read it , it get the same string but by replacing + with empty charFor example if i pass query like ../Page.aspx?data=sdf1+sdf then in page load I read data by data = Request.QueryString["data"] it will get as below data ="sdf1 sdf"
I solve the problem by replacing any empty char with + .. But Is there any problem that cause that ? and Is my solution by replacing empty char with + is the best solution in all cases?
I have a gridview and I would like to be able to programatically change the HeaderText of it's columns (probably in the DataBinding event). I know this can normally be achieve with something like this:
myGrid.Columns[0].HeaderText = "My Header Text";
However, the gridview in question is actually nested within another gridview (via template column). So I can't access it directly. I'm trying to use the FindControl method to access it, but so far that isn't working.
I have two different functions which are used to generate two different report on one gridview. In otherwords, in my design, I have a calendar event which is used to generate a report on the gridview and I have a dropdownlist which is used to generate a different report on the same gridview, so depending on the control that is clicked on depends on the report being generated. Now I would like a situation where my gridview rowdatabound is only applied to the dropdownlist report not the calendar event report. How can i go about doing so.
View 1 RepliesI cannot figure out why HeaderText or validation controls always fallback to default culture - even though rest of the controls are in correct culture.
I have a GridView with HeaderText specified in this way>
<asp:BoundField DataField="totalSales" HeaderText="<%$ Resources:Strings,TotalSales %>" />
In the same way I have validation controls and they can't be localized.
Only this syntax does work: <%= Resources.Strings.Payments %>
I set different culture in Master page using this statement in Page_Init
Me.Page.Culture = "pl-PL"
Me.Page.UICulture = "pl-PL"
Can I do something like this:
<asp:BoundField DataField="Field1"
HeaderText='<% IF(Eval("Field2").ToString().SubString(3,4).Equals("Text3"),"Text1","Text2") %>'
SortExpression="Field1" />
With the goal of having the header of Field1 be Text1 when the 4th-7th characters of Field2 = Text3 and Text2 otherwise?
I tried it and it just put "'<%IF(Eval("Field2").ToString().SubString(3,4).Equals("Text3"),"Text1","Text2") %>'" as the actual header string!
I have a gridview with a hyperlinkfield inside of it. There is a dropdownlist that re-databinds the gridview onselectedindexchanged. I'm using the datanavigateurlformatstring attribute of the hyperlinkfield to make the url, and in in most cases it works as it should. HOWEVER, when one particular item is selected from the dropdownlist the associated links that are supposed to be created in the hyperlinkfield do not work. They arent actually clickable. In the source they have no href (which is what the datanavigateurlformatstring is supposed to set along with datanavigateurlfields). I have debugged to see that before and after databinding the information going into the control is correct, but still it doesnt work. In every other case it works.

Apparently all goes weel, because i ca see, in a a debug session, the control initial value, and after i change it, the value changes.
I have an gridview with 3 columns. As default I entered for each columnns an headertext, but depending on an language parameter in the data the headertext is changed on page_load with a SetLabels function.
Recently I added an templatefield textbox with an autopostback=true and an ontextchanged event :
When a user changes the text in the textbox all events are executed properly BUT my headertext is set back to the default value (from the .ascx) even tho page_load event is executing properly WITH the SETLABELS function.
I have a gridview with two bound fields. On clicking a button i want to display the values in first row of gridview in two textboxes. But if gridview cell is empty i am getting the text in textbox to which the value of cell is given as -' 'i know my problem will be solved if i use the template fields instead. But i want a solution while maintaining the bound fields ,if any.
View 2 RepliesIs tehre anyway to set the HeaderText dynamically on a gridview? I'm trying the below, it kind of works, but the problem is on the initial load nothing shows up, but when I postback then the new text populates:
grdvMyTest.HeaderRow.Cells[5].Text = GetTheCalculatedDate();
I've tried that in both Page_Load and grdMyTest_Load, but same thing happens in both. When the page initial loads the column header text is blank, when I click something causing a postback it pops up. I don't have a IsPostBack check around that line, so it should be running regradless. I'm guessing I'm doing it at the wrong event, either too eariler or too late.
I am using Templates in GridView, but now I have to change the "HeaderText" of each column from code behind. I don't have <HeaderTemplate> so therefore I cannot use FndControl() in header row.
Is there a way to change the HeaderText of each colum without using <HeaderTemplate>
Here are the templates of the GridView which I am using

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.
I am working with a gridview that pulls data from a SQL database based on selections in dropdown lists. The source table has six columns for attributes of the selection, but depending on what is chosen, there could be anywhere from one to six of those that are empty (all null values). When the column is empty, I would like to have it hidden so the page is less clunky and confusing.
I've searched around for an answer for the past couple days, but what I have found so far is either related to hiding columns that you know are empty which I will not know or removing them in the SQL code which I think doesn't work if the column is called for in the gridview code and doesn't exist in the query.
Actually i want that HeaderText of gridview should be as column name of datatable, which i assign to that perticular column of gridview.
I have templatefield in that column and AutoGeneratedColumn is false
I have a GridView whose AutoGenerateColumns="False". However, I don't want to statically specify the HeaderText for the columns in HTML markup. Rather I'd like to set the HeaderText to be the name of the underlying SQLDataSource column name. How can I do this?

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 grid that is built as well as populated dynamically through c# code. The grid has 3 columns(3 bound fields). And data is being populated in those bound fields through c# code programatically.
Elaborating my question: I have 3 bound field columns(col1, col2 & col3) . I have to increase the rowspan of col2 and col3 headertext's to 2 i.e I want the col2 and col3 header texts to span across two row cells. But the col1 header text should span across just 1 row. And the extra rowscell that is created under col1 due to the increase in the rowspans (of col2 and col3 boundfield headertexts) should be populated with some random text, i.e something like XXXXX

View 6 Replieshow can i access the headertext of a templatefield of a gridview on mouseover and display it in a label control?
View 4 RepliesgvOff.DataSource = o.ViewData(dCity.SelectedValue);
gvOff.DataBind();
gvOff.Columns[0].HeaderText = "ZZZZZZZZ";
gvOff.Columns[1].HeaderText = "YYYYYYYY";
gvOff.Columns[2].HeaderText = "XXXXXXXX";
Header count is correct.
AutoGenerateColumns: Flase/True ( i tried both)
If i remove the gvOff.Columns[index].HeaderText portions, GridView works fine, but when i put the gvOff.Columns[0].HeaderText, i get the exceptional error.
, i couldn't solve it. If you need further info, inform me.
EDITED:
Hold on! I commented the HeaderText portion and tested
int i = gvOffer.Columns.Count;
I found count is 0 eventhough the columns print out with DataBind()... Why?
NOTE: AutoColumn in this case is set to true. I guess i will have to edit the column
names from DataTable.

View 2 RepliesSo the case is this:
The user can provide a group of strings for a propert. ex:
DaysNeeded ="Sunday,Tuesday,Friday,Saturday";
In the actual UI, the days of the week are available as check boxes. I'm trying to provide a way so that the user can also set the days needed in the code behind through a property.
Now my query is, which strategy is the best way to execute certain pieces of code that are respective to the days that the user have provided. Meaning, the DaysNeeded property has sunday,Tuesday, Friday and Saturday. Each day has certain piece of code to be executed. If i have to have a forloop with a switch case for each day of the week, i feel it would cost more as i have to run the for loop, the number of days the user has given.
Is there a way that i can run a single code that matches all the set of days the user has given and run the respective code pieces?
If the gridview binds to empty dataset, I need to still show a gridview so that users can ADD more using the textfields in the bottom of the footer template. Since the gridview is empty it won't bind not allowing rendering of the <footer template> I guess I should create a empty dataset if the gridview is empty. How do I check for this and can this be done in GridviewRowEventArgs

I want to save data to a different table. My save is working fine but the challenge is that it saves empty cells as well.I will like to save only QTyDelivered cell with value. Any empty QTyDelivered cell should be ignored (which means the row of QTyDelivered cell that is empty will not be saved) .How can i achieve this?
